Unsupported operation. Method not found. The exception thrown was: MissingPluginException

[wellbranding]

Just added a plugin to android and immediately got an internal error:

MethodChannelFilePicker] Unsupported operation. Method not found. The exception thrown was: MissingPluginException(No implementation found for method any on channel miguelruivo.flutter.plugins.filepicker)
E/flutter ( 6524): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: MissingPluginException(No implementation found for method any on channel miguelruivo.flutter.plugins.filepicker)

I initially used grade 4.1.2, ten switched to recommended 4.0.1, and wrapped properties to 6.1.1, but the issue exists.

Hi, I’m sorry you’re experiencing this, but it’s likely related with your project dependencies.

Try cleaning, checking the wiki’s troubleshooting or looking for similar issues here in the repo (which are reported sometimes and ending up fixed by the reporters themselves).

I’m sorry for any inconvenience.

MissingPluginException(No implementation found for method any on channel miguelruivo.flutter.plugins.filepicker)

One situation when the above exception occurs for Android is when you have overridden the method MainActivity.configureFlutterEngine without invoking super.configureFlutterEngine

This might happen if you are using a PlatformView and have followed the documentation at https://github.com/flutter/flutter/wiki/Hybrid-Composition which currently does not invoke super.configureFlutterEngine
unlike the documentation at https://docs.flutter.dev/platform-integration/android/platform-views?tab=android-platform-views-kotlin-tab which does invoke super.configureFlutterEngine

@TomasJohansson What about in swift? I have built some method channels and my thoughts were somehow that my use of them had overridden the method channel the file picker was working from. Is that true, and where could that be corrected in the swift code?
