Flutter 与 Android

说明

在本人项目中以 aar 的方式，将Flutter接入Android。本文旨在记录，不为教学，不定时更新。

Flutter与Android交互

退出Flutter Activity

Android:

class MyClass(context: Context, route: String) : AbstractFlutterPage(context, route) {

    override fun getMethodChannelName(): String {
        return "my_package_name/way"
    }

    override fun onMethodCall(methodCall: MethodCall?, result: MethodChannel.Result?) {
        methodCall?.let {
            when {
                methodCall.method == "popNativePage" -> {
                    if(mContext is Activity){
                        mContext.finish()
                    }
                    result?.success("")
                }

                else -> result?.notImplemented()
            }
        }
    }
}

Flutter:

static const methodChannel =
    const MethodChannel('my_package_name/way');
    
void _invokeNativePop() async {
    ifYouHaveReturnValue = await methodChannel.invokeMethod("popNativePage");
}

Android调起Flutter

项目中使用Arouter作为路由框架。

Android：

override fun onClick(v: View?) {
        when (v?.id) {
            R.id.id_name -> {
                ARouter.getInstance().build(ARouterConstants.FLUTTER_ACTIVITY)
                    .withRoute(ARouterConstants.Flutter_Routes.WAY).navigation()
            }
        }
}

Flutter:

void main() => runApp(_widgetForRoute(ui.window.defaultRouteName));

Widget _widgetForRoute(String route) {
  switch (route) {
    case 'WAY':
      return new MaterialApp(
        title: 'MyName',
        theme: new ThemeData(
          primarySwatch: Colors.blue,
          highlightColor: Color(0xFF7B40FF),
          primaryColor: Color(0xFF6132CB),
          disabledColor: Color(0xFFD7C6FF),
        ),
        home: MyView(),
      );
  default:
      return Center(
        child: Text('Unknown route: $route', textDirection: TextDirection.ltr),
      );
  }
}
