invalid item 'Flutter for Android' in the dependencies list

[alexobviously]

I've been working with Flutter for a while and have made a number of projects with no problems, but I just started trying to create a new one and have run into what seems to be an impassable problem.

There are a number of things happening as far as I can tell, but I think this is at the core of it:
In Android Studio, in project structure (cmd+;), I have this in the 'Problems' tab:
Module a_test_app_android: invalid item 'Flutter for Android' in the dependencies list

I first encountered this in the live project that I'm trying to create, but have since tried to do it with a completely blank project and it's still there.

Note: this test project actually will still run! However, in my live project, I'm encountering some other problems that I'm fairly sure are caused by this and are the reason I realised it was broken in the first place, lots of MissingPluginExceptions and these do crash it:

E/flutter (10005): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/package_info)
E/flutter (10005): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method getTemporaryDirectory on channel plugins.flutter.io/path_provider)
E/flutter (10005): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method getDatabasesPath on channel com.tekartik.sqflite)

etc.

Investigating this led to me to GeneratedPluginRegistrant.java, which looks like this in my test project:

And this led me to

I have tried:

• flutter clean
• reinstalling flutter
• different flutter channels
• reinstalling android studio
• downgrading to an android studio that I know worked

None of these change anything; I always have this missing Flutter for Android issue in project structure:

A project that I created before this issue started happening, with all the same packages and virtually the same implementation (new project is a variant of the old project) is still working fine.

! Doctor found issues in 2 categories.

You'll notice that in my doctor log it also says that the flutter and dart plugins are not installed for Android Studio (don't worry about IDEA, I don't use it for flutter), but they definitely are, and I wasn't receiving this warning until recently either, so I feel it may be related, but I'm not really sure.

I'm on Android Studio 4.1.1, on OSX Mojave 10.14.6

This is not an error it is just a warning caused by a new IntelliJ/Android Studio upgrade where they changed the path of the plugins and Flutter can't find/detect them. You can still using Flutter without problems.

Investigating this led to me to GeneratedPluginRegistrant.java, which looks like this in my test project:

Those are red because you opened Android related files using an IDE that does not have an Android plugin, we recommend Android Studio to open such files to get auto completion and some more benefits. This is not an problem as well.

Note: this test project actually will still run! However, in my live project, I'm encountering some other problems that I'm fairly sure are caused by this and are the reason I realised it was broken in the first place, lots of MissingPluginExceptions and these do crash it:

The crash related to path_provider is known and there is already a issue to track it #46679. For the sqflite package, please open an issue in their repository because it is not part of Flutter team plugins. For package_info there is an open issue #69009, please share your thoughts there.

Module a_test_app_android: invalid item 'Flutter for Android' in the dependencies list

Please open a specific issue related to this issue.

Closing this because this single issue talks about many issues and some of them are already reported, opened or they are invalid.

This is Android Studio.

I'm aware that these plugins have had these issues reported because I've been through all of the proposed solutions and none of them worked for me.

The crux of the issue is this:
I can take code that works in a previous project with the same packages, and put it in a new project with those packages and it will throw MissingPluginExceptions. Therefore it must be something to do with how Android Studio/flutter create generates the projects in recent versions, I assume.

I would happily open a specific issue for this, but I'm not quite sure how to phrase it or what other information to provide?

[pedromassangocode]

I suggest you to focus in describing how to reproduce the issue and talk about one single issue. I just closing this because it is too confuse and talks about so many issue at the same time.
