flutter_addtoapp_bridge #

communications between flutter and native

Getting Started #

This project is a starting point for a Flutter plug-in package, a specialized package that includes platform-specific implementation code for Android and/or iOS.

For help getting started with Flutter development, view the online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.

Create Flutter Plugin Project #

flutter create --org com.codesdancing.flutter.addtoapp.bridge --template=plugin --platforms=android,ios -a kotlin -i objc flutter_addtoapp_bridge=

Open example/android or example/ios #

build example flutter before open example/ios, don't just open flutter_addtoapp_bridge/android or flutter_addtoapp_bridge/ios.

cd example
flutter build ios --no-codesign -v

Waiting for another flutter command to release the startup lock.. #

killall -9 dart

Usage(flutter call android/ios) #

• dart

try {
  dynamic result = await _flutterAddtoappBridgePlugin.open("toast", "Hi, I am from flutter!");
  if (kDebugMode) {
    print("putPlatformValue result=$result");
  }
} on PlatformException {
  platformVersion = 'Failed to get platform version.';
}

• ios(objectivec)
