如何从颤振插件本机代码返回小部件？

Question

I am trying to learn flutter plugin development as I will need it anyway to act seriously with porting native SDKs.

The point is, I don't really know how to return an Android Activity as a Widget that could be placed in any Column or Row etc.

For now, all I did was to port Android's Toast functionality.

The flutter maps plugin seems to be little overcomplicated, while I am learning it I still look for a simpler example of how to convert native layouts into Flutter widgets.

You can not return Android Activity as a Widget in flutter. Flutter plugins or flutter platform channels allow only basic datatypes or codecs between native, given here .

You can still run an activity or display any widget by calling a method over platform channel, and once that activity is completed you can send result back to flutter code over the bridge using "MethodChannel.Result" object provided in method call. like:

methodResult.success(data);

You can refer ImagePicker plugin for details about how to run new Activity and add onActivityResult delegates to flutter registrar to handle and pass activity's result back to flutter.

See this guide for hosting native Android and iOS views in your Flutter app. For example, if you need to host a view from a native Android or iOS SDK in your flutter app.
