This PR introduces a new protocol `FlutterImplicitEngineDelegate`, which
adds a callback called `didInitializeImplicitFlutterEngine`, which
returns a new interface called `FlutterImplicitEngineBridge`.
This was added to expose parts of an implicit `FlutterEngine`, such as
when created from a `FlutterViewController` in a storyboard.
``` swift diff
@objc class AppDelegate: FlutterAppDelegate, FlutterImplicitEngineDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
func didInitializeImplicitFlutterEngine(_ engineBridge: FlutterImplicitEngineBridge) {
// Register plugins with `engineBridge.pluginRegistry`
GeneratedPluginRegistrant.register(with: engineBridge.pluginRegistry)
// Create method channels with `engineBridge.applicationRegistrar.messenger()`
let batteryChannel = FlutterMethodChannel(
name: "samples.flutter.dev/battery",
binaryMessenger: engineBridge.applicationRegistrar.messenger()
)
...
// Create platform views with `engineBridge.applicationRegistrar.messenger()`
let factory = FLNativeViewFactory(messenger: engineBridge.applicationRegistrar.messenger())
...
}
```
This PR also refactors `FlutterPluginRegistrar` into 3 separate
protocols:
* `FlutterBaseRegistrar`
* `FlutterApplicationRegistrar`
* `FlutterPluginRegistrar`
Most methods are moved from `FlutterPluginRegistrar` to
`FlutterBaseRegistrar` and then `FlutterPluginRegistrar` and
`FlutterApplicationRegistrar` inherit from `FlutterBaseRegistrar`.
`FlutterPluginRegistrar` also has additional methods specific to it -
there are no meaningful/breaking changes to `FlutterPluginRegistrar`.
Fixes https://github.com/flutter/flutter/issues/173357.
