**THIS IS A BREAKING CHANGE.** See below for migration steps for existing projects. Previously, Flutter app code was built as a raw dylib on iOS. Dynamic libraries outside of a framework bundle are not supported on iOS, except for the system Swift libraries provided by Xcode. See: https://developer.apple.com/library/content/technotes/tn2435/_index.html#//apple_ref/doc/uid/DTS40017543-CH1-TROUBLESHOOTING_BUNDLE_ERRORS-EMBEDDED__DYLIB_FILES * Migrates Xcode build from app.dylib to App.framework * Migrates flutter create template * Migrates example projects Migration steps for existing projects ===================================== The following steps should be taken from the root of your Flutter project: 1. Edit `ios/.gitignore`: add `/Flutter/App.framework` on a new line. 2. In the Xcode project navigator, remove `app.dylib` from the Flutter folder. Delete this file from the `ios/Flutter` directory in your project. 3. Run a build to generate `ios/Flutter/App.framework`. From the command line, run `flutter build ios`. If you have not configured app signing in Xcode, an alternative method is to open the simulator, then run `flutter run -d iP`. 4. In the Xcode project navigator, select the `Runner` project. In the project settings that are displayed in the main view, ensure that the `Runner` target is selected. You can verify this by exposing the sidebar using the [| ] icon in the upper-left corner of the main view. 5. Select the *General* tab in the project settings. Under the *Embedded Binaries* section, click '+' to add `App.framework`. In the sheet that drops down, click the *Add Other...* button. Navigate to the `ios/Flutter` directory and select `App.framework`. Click *Open*. In the sheet that drops down, select *Create folder references*, then click *Finish*. 6. In the project settings, verify that `App.framework` has been added to the *Embedded Binaries* and *Linked Frameworks and Libraries* lists. 7. In the Xcode project navigator, drag `App.framework` under the Flutter folder. 8. In the Xcode project navigator, select `Flutter` then from the *File* menu, select *Add Files to "Runner"...*. Navigate to the `ios/Flutter` directory, select `AppFrameworkInfo.plist` and click the *Add* button. 9. From the command line, in your project directory, run `flutter build clean`, then `flutter run`. At this point your project should be fully migrated.
Flutter Examples
This directory contains several examples of using Flutter. Each of these is an individual Dart application package.
To run an example, use flutter run inside that example's directory. See the
getting started guide to install
the flutter tool.
Tip: To see examples of how to use a specific Flutter framework class,
copy and paste a URL with this format in your browser. Replace foo with the
classname you are searching for (for example, here's the query for examples of
the AppBar class).

Available examples include:
-
Hello, world The hello world app is a basic app that shows the text "hello, world."
-
Flutter gallery The flutter gallery app showcases Flutter's implementation of material design.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. There is no main.dart in this directory because each file is a standalone example. To run a particular file, use
flutter run -t filename.dart.
