## NEXT * Updates minimum Flutter version to 3.0. ## 2.0.1 * Improves error message when a platform interface class is used before `WebViewPlatform.instance` has been set. ## 2.0.0 * **Breaking Change**: Releases new interface. See [documentation](https://pub.dev/documentation/webview_flutter_platform_interface/2.0.0/) and [design doc](https://flutter.dev/go/webview_flutter_4_interface) for more details. * **Breaking Change**: Removes MethodChannel implementation of interface. All platform implementations will now need to create their own by implementing `WebViewPlatform`. ## 1.9.5 * Updates code for `no_leading_underscores_for_local_identifiers` lint. ## 1.9.4 * Updates imports for `prefer_relative_imports`. ## 1.9.3 * Updates minimum Flutter version to 2.10. * Removes `BuildParams` from v4 interface and adds `layoutDirection` to the creation params. ## 1.9.2 * Fixes avoid_redundant_argument_values lint warnings and minor typos. * Ignores unnecessary import warnings in preparation for [upcoming Flutter changes](https://github.com/flutter/flutter/pull/106316). * Adds missing build params for v4 WebViewWidget interface. ## 1.9.1 * Ignores unnecessary import warnings in preparation for [upcoming Flutter changes](https://github.com/flutter/flutter/pull/104231). ## 1.9.0 * Adds the first iteration of the v4 webview_flutter interface implementation. * Removes unnecessary imports. ## 1.8.2 * Migrates from `ui.hash*` to `Object.hash*`. * Updates minimum Flutter version to 2.5.0. ## 1.8.1 * Update to use the `verify` method introduced in platform_plugin_interface 2.1.0. ## 1.8.0 * Adds the `loadFlutterAsset` method to the platform interface. ## 1.7.0 * Add an option to set the background color of the webview. ## 1.6.1 * Revert deprecation of `clearCookies` in WebViewPlatform for later deprecation. ## 1.6.0 * Adds platform interface for cookie manager. * Deprecates `clearCookies` in WebViewPlatform in favour of `CookieManager#clearCookies`. * Expanded `CreationParams` to include cookies to be set at webview creation. ## 1.5.2 * Mirgrates from analysis_options_legacy.yaml to the more strict analysis_options.yaml. ## 1.5.1 * Reverts the addition of `onUrlChanged`, which was unintentionally a breaking change. ## 1.5.0 * Added `onUrlChanged` callback to platform callback handler. ## 1.4.0 * Added `loadFile` and `loadHtml` interface methods. ## 1.3.0 * Added `loadRequest` method to platform interface. ## 1.2.0 * Added `runJavascript` and `runJavascriptReturningResult` interface methods to supersede `evaluateJavascript`. ## 1.1.0 * Add `zoomEnabled` functionality to `WebSettings`. ## 1.0.0 * Extracted platform interface from `webview_flutter`.

# Master channel samples In this directory, you'll find samples that target Flutter's master channel. They may take advantage of new SDK features that haven't landed in the stable channel, and they may crash, lock up your machine, or otherwise fail to run correctly. In other words, consider everything in this directory to be an experiment. We're maintaining these samples here so that folks can see some of Flutter's upcoming features as they evolve and get a sense for how they'll eventually be used. If you'd like to run the apps, make sure to switch to the master channel first: ```bash flutter channel master flutter upgrade ``` When you're done, use this command to return to the safety of the stable channel: ```bash flutter channel stable ``` ## Want more info about the repo in general? See the [README](../README.md) in the repo's root folder.

# FFIgen + JNIgen pedometer This is a demo for some of our tooling around calling platform APIs directly from dart code. This repository represents a demo of a plugin that leverages FFIgen & JNIgen. There is also an example pedometer app that uses the bindings generated from these tools. - [FFIgen](https://pub.dev/packages/ffigen) is used to generate bindings for C, Objective-C and Swift APIs. - [JNIgen](https://pub.dev/packages/jnigen) is used to generate bindings for Java and Kotlin APIs. **These tools are both experimental and are currently a work in progress.** If you find any issues or have feedback, please file it on the corresponding GitHub repositories. ## Re-generating bindings The bindings that allow the Dart code to call the platform code have already been generated in the [`\lib` folder](./lib). You can regenerate them by following the steps below: ### FFIgen Configuration of FFIgen for the [CoreMotion framework](https://developer.apple.com/documentation/coremotion) is in the [`ffigen.yaml` file](./ffigen.yaml). FFIgen currently does not support autogenerating code to handle callbacks. So, there are a few extra steps needed to appropriately handle callbacks in Objective-C. You can read more about this limitation on [dart.dev](https://dart.dev/interop/objective-c-interop#callbacks-and-multithreading-limitations). ```bash dart run ffigen --config ffigen.yaml ``` ### JNIgen Configuration of JNIgen for the [HealthConnect API](https://developer.android.com/guide/health-and-fitness/health-connect) is in the [`jnigen.yaml` file](./jnigen.yaml). 1. Build an Android APK file from the example app. Currently, JNIgen requires at least one APK build to obtain the classpaths of Android Gradle libraries. ```bash cd example && flutter build apk ``` 2. Return to the `/pedometer` directory and run `jnigen`: ```bash cd .. && dart run jnigen --config jnigen.yaml ``` ## Running the example app The example app is located in the [`/example`](./example) directory, and the following commands assume they are being run from that location. Note that step counting is only available on physical devices. ### iOS - Run `flutter run` and choose your physical device. - Allow the *pedometer* app access to step counting. ### Android - Make sure that [Google Fit](https://play.google.com/store/apps/details?id=com.google.android.apps.fitness) is installed (to ensure that steps are being counted). - Run `flutter run` and choose your physical device. - Install [Health Connect](https://play.google.com/store/apps/details?id=com.google.android.apps.healthdata) and grant access to Google Fit and the *jni_demo* app. ## Project structure * `src`: Contains the native source code, and a `CMakeLists.txt` file for building that source code into a dynamic library. * `lib`: Contains the Dart code that defines the API of the plugin and calls into the native code using `dart:ffi`. * platform folders (`ios` etc.): Contain the build files for building and bundling the native code library with the platform application. * `example`: Contains the native source code for building that source code into a dynamic library.

Instead, isolates communicate by message passing. * * Each thread keeps track of its current isolate, which is the * isolate which is ready to execute on the current thread. The * current isolate may be NULL, in which case no isolate is ready to * execute. Most of the Dart apis require there to be a current * isolate in order to function without error. The current isolate is * set by any call to Dart_CreateIsolateGroup or Dart_EnterIsolate. */ typedef struct _Dart_Isolate* Dart_Isolate; typedef struct _Dart_IsolateGroup* Dart_IsolateGroup; /** * An object reference managed by the Dart VM garbage collector. * * Because the garbage collector may move objects, it is unsafe to * refer to objects directly. Instead, we refer to objects through * handles, which are known to the garbage collector and updated * automatically when the object is moved. Handles should be passed * by value (except in cases like out-parameters) and should never be * allocated on the heap. * * Most functions in the Dart Embedding API return a handle. When a * function completes normally, this will be a valid handle to an * object in the Dart VM heap. This handle may represent the result of * the operation or it may be a special valid handle used merely to * indicate successful completion. Note that a valid handle may in * some cases refer to the null object. * * --- Error handles --- * * When a function encounters a problem that prevents it from * completing normally, it returns an error handle (See Dart_IsError). * An error handle has an associated error message that gives more * details about the problem (See Dart_GetError). * * There are four kinds of error handles that can be produced, * depending on what goes wrong: * * - Api error handles are produced when an api function is misused. * This happens when a Dart embedding api function is called with * invalid arguments or in an invalid context. * * - Unhandled exception error handles are produced when, during the * execution of Dart code, an exception is thrown but not caught. * Prototypically this would occur during a call to Dart_Invoke, but * it can occur in any function which triggers the execution of Dart * code (for example, Dart_ToString). * * An unhandled exception error provides access to an exception and * stacktrace via the functions Dart_ErrorGetException and * Dart_ErrorGetStackTrace. * * - Compilation error handles are produced when, during the execution * of Dart code, a compile-time error occurs. As above, this can * occur in any function which triggers the execution of Dart code. * * - Fatal error handles are produced when the system wants to shut * down the current isolate. * * --- Propagating errors --- * * When an error handle is returned from the top level invocation of * Dart code in a program, the embedder must handle the error as they * see fit. Often, the embedder will print the error message produced * by Dart_Error and exit the program. * * When an error is returned while in the body of a native function, * it can be propagated up the call stack by calling * Dart_PropagateError, Dart_SetReturnValue, or Dart_ThrowException. * Errors should be propagated unless there is a specific reason not * to. If an error is not propagated then it is ignored. For * example, if an unhandled exception error is ignored, that * effectively "catches" the unhandled exception. Fatal errors must * always be propagated. * * When an error is propagated, any current scopes created by * Dart_EnterScope will be exited. * * Using Dart_SetReturnValue to propagate an exception is somewhat * more convenient than using Dart_PropagateError, and should be * preferred for reasons discussed below. * * Dart_PropagateError and Dart_ThrowException do not return. Instead * they transfer control non-locally using a setjmp-like mechanism. * This can be inconvenient if you have resources that you need to * clean up before propagating the error. * * When relying on Dart_PropagateError, we often return error handles * rather than propagating them from helper functions. Consider the * following contrived example: * * 1 Dart_Handle isLongStringHelper(Dart_Handle arg) { * 2 intptr_t* length = 0; * 3 result = Dart_StringLength(arg, &length); * 4 if (Dart_IsError(result)) { * 5 return result; * 6 } * 7 return Dart_NewBoolean(length > 100); * 8 } * 9 * 10 void NativeFunction_isLongString(Dart_NativeArguments args) { * 11 Dart_EnterScope(); * 12 AllocateMyResource(); * 13 Dart_Handle arg = Dart_GetNativeArgument(args, 0); * 14 Dart_Handle result = isLongStringHelper(arg); * 15 if (Dart_IsError(result)) { * 16 FreeMyResource(); * 17 Dart_PropagateError(result); * 18 abort(); // will not reach here * 19 } * 20 Dart_SetReturnValue(result); * 21 FreeMyResource(); * 22 Dart_ExitScope(); * 23 } * * In this example, we have a native function which calls a helper * function to do its work. On line 5, the helper function could call * Dart_PropagateError, but that would not give the native function a * chance to call FreeMyResource(), causing a leak. Instead, the * helper function returns the error handle to the caller, giving the * caller a chance to clean up before propagating the error handle. * * When an error is propagated by calling Dart_SetReturnValue, the * native function will be allowed to complete normally and then the * exception will be propagated only once the native call * returns. This can be convenient, as it allows the C code to clean * up normally. * * The example can be written more simply using Dart_SetReturnValue to * propagate the error. * * 1 Dart_Handle isLongStringHelper(Dart_Handle arg) { * 2 intptr_t* length = 0; * 3 result = Dart_StringLength(arg, &length); * 4 if (Dart_IsError(result)) { * 5 return result * 6 } * 7 return Dart_NewBoolean(length > 100); * 8 } * 9 * 10 void NativeFunction_isLongString(Dart_NativeArguments args) { * 11 Dart_EnterScope(); * 12 AllocateMyResource(); * 13 Dart_Handle arg = Dart_GetNativeArgument(args, 0); * 14 Dart_SetReturnValue(isLongStringHelper(arg)); * 15 FreeMyResource(); * 16 Dart_ExitScope(); * 17 } * * In this example, the call to Dart_SetReturnValue on line 14 will * either return the normal return value or the error (potentially * generated on line 3). The call to FreeMyResource on line 15 will * execute in either case. * * --- Local and persistent handles --- * * Local handles are allocated within the current scope (see * Dart_EnterScope) and go away when the current scope exits. Unless * otherwise indicated, callers should assume that all functions in * the Dart embedding api return local handles. * * Persistent handles are allocated within the current isolate. They * can be used to store objects across scopes. Persistent handles have * the lifetime of the current isolate unless they are explicitly * deallocated (see Dart_DeletePersistentHandle). * The type Dart_Handle represents a handle (both local and persistent). * The type Dart_PersistentHandle is a Dart_Handle and it is used to * document that a persistent handle is expected as a parameter to a call * or the return value from a call is a persistent handle. * * FinalizableHandles are persistent handles which are auto deleted when * the object is garbage collected. It is never safe to use these handles * unless you know the object is still reachable. * * WeakPersistentHandles are persistent handles which are automatically set * to point Dart_Null when the object is garbage collected. They are not auto * deleted, so it is safe to use them after the object has become unreachable. */ typedef struct _Dart_Handle* Dart_Handle; typedef Dart_Handle Dart_PersistentHandle; typedef struct _Dart_WeakPersistentHandle* Dart_WeakPersistentHandle; typedef struct _Dart_FinalizableHandle* Dart_FinalizableHandle; // These structs are versioned by DART_API_DL_MAJOR_VERSION, bump the // version when changing this struct. typedef void (*Dart_HandleFinalizer)(void* isolate_callback_data, void* peer); /** * Is this an error handle? * * Requires there to be a current isolate. */ DART_EXPORT bool Dart_IsError(Dart_Handle handle); /** * Is this an api error handle? * * Api error handles are produced when an api function is misused. * This happens when a Dart embedding api function is called with * invalid arguments or in an invalid context. * * Requires there to be a current isolate. */ DART_EXPORT bool Dart_IsApiError(Dart_Handle handle); /** * Is this an unhandled exception error handle? * * Unhandled exception error handles are produced when, during the * execution of Dart code, an exception is thrown but not caught. * This can occur in any function which triggers the execution of Dart * code. * * See Dart_ErrorGetException and Dart_ErrorGetStackTrace. * * Requires there to be a current isolate. */ DART_EXPORT bool Dart_IsUnhandledExceptionError(Dart_Handle handle); /** * Is this a compilation error handle? * * Compilation error handles are produced when, during the execution * of Dart code, a compile-time error occurs.

# ios_app_clip A sample project demonstrating integration with iOS App Clip. The App Clip target is rendered by Flutter and uses a plugin. ## Intent 1. Demonstrate it's possible to produce iOS App Clip targets rendered in Flutter. 2. Serve as a canonical example to test the App Clip scenario. 3. Let users validate their integration steps when following the guide at [flutter.dev/docs/development/platform-integration/ios-app-clip](https://flutter.dev/docs/development/platform-integration/ios-app-clip) ## To run In order to run. 1. `flutter build ios --config-only` 1. `open Runner.xcworkspace` 1. Inside Xcode, select the `AppClip` target from the scheme dropdown 1. Select an iOS 16 or higher device 1. Select a development team as needed 1. Press run in Xcode to run ## Questions/issues If you have a general question about iOS App Clips in Flutter, the best places to go are: * [The FlutterDev Google Group](https://groups.google.com/forum/#!forum/flutter-dev) * [The Flutter Gitter channel](https://gitter.im/flutter/flutter) * [StackOverflow](https://stackoverflow.com/questions/tagged/flutter) If you run into an issue with the sample itself, please file an issue in the [main Flutter repo](https://github.com/flutter/flutter/issues).

# Material 3 Demo This sample Flutter app showcases Material 3 features in the Flutter Material library. These features include updated components, typography, color system and elevation support. The app supports light and dark themes, different color palettes, as well as the ability to switch between Material 2 and Material 3. For more information about Material 3, the guidance is now live at https://m3.material.io/. This app also includes new M3 components such as IconButtons, Chips, TextFields, Switches, Checkboxes, Radio buttons and ProgressIndicators. # Preview <img width="400" alt="Screen Shot 2022-08-12 at 12 00 28 PM" src="https://user-images.githubusercontent.com/36861262/184426137-47b550e1-5c6e-4bb7-b647-b1741f96d42b.png"><img width="400" alt="Screen Shot 2022-08-12 at 12 00 38 PM" src="https://user-images.githubusercontent.com/36861262/184426154-063a39e8-24bd-40be-90cd-984bf81c0fdf.png"> # Features ## Icon Buttons on the Top App Bar <img src="https://user-images.githubusercontent.com/36861262/166506048-125caeb3-5d5c-4489-9029-1cb74202dd37.png" width="25"/> Users can switch between a light or dark theme with this button. <img src="https://user-images.githubusercontent.com/36861262/166508002-90fce980-d228-4312-a95f-a1919bb79ccc.png" width="25" /> Users can switch between Material 2 and Material 3 for the displayed components with this button. <img src="https://user-images.githubusercontent.com/36861262/166511137-85dea8df-0017-4649-b913-14d4b7a17c2f.png" width="25" /> This button will bring up a pop-up menu that allows the user to change the base color used for the light and dark themes. This uses a new color seed feature to generate entire color schemes from a single color. ## Component Screen The default screen displays all the updated components in Material 3: AppBar, common Buttons, Floating Action Button(FAB), Chips, Card, Checkbox, Dialog, NavigationBar, NavigationRail, ProgressIndicators, Radio buttons, TextFields and Switch. ### Adaptive Layout Based on the fact that NavigationRail is not recommended on a small screen, the app changes its layout based on the screen width. If it's played on iOS or Android devices which have a narrow screen, a Navigation Bar will show at the bottom and will be used to navigate. But if it's played as a desktop or a web app, a Navigation Rail will show on the left side and at the same time, a Navigation Bar will show as an example but will not have any functionality. Users can see both layouts on one device by running a desktop app and adjusting the screen width. ## Color Screen With Material 3, we have added support for generating a full color scheme from a single seed color. The Color Screen shows users all of the colors in light and dark color palettes that are generated from the currently selected color. ## Typography Screen The Typography Screen displays the text styles used in for the default TextTheme. ## Elevation Screen The Elevation screen shows different ways of elevation with a new supported feature "surfaceTintColor" in the Material library.
