一. Android跳转到Flutter
1. 继承FlutterFragmentActivity，并构建Intent
class NewHouseMainActivity : FlutterFragmentActivity() {
// 通道
private lateinit var methodChannel: MethodChannel
companion object {
private const val EXTRA_INITIAL_ROUTE = "route"
private const val EXTRA_BACKGROUND_MODE = "background_mode"
private const val EXTRA_DESTROY_ENGINE_WITH_ACTIVITY = "destroy_engine_with_activity"
/**
* 构建Intent
*/
fun buildIntent(context: Context,routeName: String): Intent {
return Intent(context,NewHouseMainActivity::class.java)
.putExtra(EXTRA_INITIAL_ROUTE,routeName)
.putExtra(EXTRA_BACKGROUND_MODE, FlutterActivityLaunchConfigs.BackgroundMode.opaque.name)
.putExtra(EXTRA_DESTROY_ENGINE_WITH_ACTIVITY, true);
}
}
}
2. 启动Activity，组件Intent
val intent = NewHouseMainActivity.buildIntent(
requireActivity(),
FlutterRouteBean().createRoute(requireContext(),FlutterParam.rout_new_house)
)
startActivity(intent)
3. 在Flutter端接收
void main() {
runApp(MyApp(homeRouteName: window.defaultRouteName));
}
Map<String, dynamic> data = convert.jsonDecode(homeRouteName!);
String? routeName = data['routeType'];
switch (routeName) {
case '/':
case '/excelSearchPage':
...
}
上面的代码写完，就可以成功的跳转到Flutter页面了
二. Flutter跳转到Android
1. 在Flutter和Android端创建通道
class NativeChannel {
static MethodChannel methodChannel = const MethodChannel("flutter_native");
// 调用Android原生的方法
static Future<void> nativeMethod(String method) async {
await methodChannel.invokeMethod(method);
}
}
override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
super.configureFlutterEngine(flutterEngine)
methodChannel = MethodChannel(flutterEngine.dartExecutor,FlutterParam.channel_name)
methodChannel.setMethodCallHandler { call, result ->
when (call.method) {
"toHomePage" -> {
startActivity(Intent(this,MainActivity::class.java))
}
}
}
}
2. 在Flutter中调用Android方法
onTap: () => {
NativeChannel.nativeMethod("toHomePage")
},
