Unresolved reference: io , Unresolved reference:MethodCallHandler

[Swan1993]

Thanks for the feedback! If your issue is related to the Flutter framework itself,
please open an issue at
github.com/flutter/flutter.

Steps to Reproduce

I am creating a plugin but the packages are not installed correctly.

It gives the following errors.

import io.flutter.embedding.engine.plugins.FlutterPlugin this error => Unresolved reference: io

class NativePathAndroidPlugin: FlutterPlugin, MethodCallHandler { this error => Unresolved reference: MethodCallHandler.

Gerdle builds correctly.
