No 'Flutter' menu option on android module

[niamh-power]

Steps to Reproduce

This is an issue in both Android Studio and IntelliJ. I've tried previous versions of both and still have the same issue.

Basically I'm wanting to do the Android X migration for our Flutter app in order to use the latest plugins, and I was having the issues detailed here https://stackoverflow.com/questions/54395491/unable-to-migrate-to-androidx/54618207 I then go to open just the android module in Android Studio rather than the whole project, and find that the Flutter option when right clicking is greyed out. To note when I do the same on the root project folder or the ios module, I get the option Open iOS module in Xcode under the non-greyed out Flutter menu item.

Any update about this?
I have the same issue. I solved it temporary opening the android folder like a separate project in Android Studio

[hariangr]

Having the same problem

UPDATE:
Seems like in my case, upgrading to Android Studio 3.3 (Which I just did prior to this error) remove the Flutter plugin
After reinstalling the Flutter plugin again, the Flutter menu did showed up, but when I clicked it, Android Studio show a error message saying 'process error, access denied'
After I restarted Android Studio, that access denied problem gone away.

Then, I clicked it again, after some process in the background Android Studio asked me to upgrade my gradle to version 4.10.1

I faced this problem because my Flutter project's Firebase plugin have some error

No update or solution found yet, @diegoalvis I did the same, opening it by going into the folder from Android Studio

any update? I have the same problem here...

I solved it. What I did is deleted the modules from my project and specify them again:

1.- File >> Project Structure...

2.- Delete all the modules
Take care here, check all the set-ups before delete them all.

3.- Create a Flutter "New Module", in the same project root
Click the "+" symbol, and in the next screen pick up "Flutter" >> "Next" button.

4.- Choose the project root
Don't change the "module name", just target the content root to your project root, and check that all it's fine.

5.- It's done
Check if the "Flutter" option is enabled now. Don't forget to import the Android module.

@Rostanxd thank you mate, it helped me, but for other ppl I want to warn to be careful with project root name, I mean if your project root name separated with '-' , then before deleting the module you should change your project root name to be with underlines '_'. In my case it was this way, 1. I changed the module name. 2. I changed the project root folder name and only after this steps I could do the steps that @Rostanxd said, if you will delete the module and start to add a new one by mentioning your project folder, which name with '-' , dart wont allow you to add such name, and you will need to close that window and go to change the project root name, but you allready deleted the module :) , this bringing many issues, that why I'm suggesting, before deleting the module be sure that everything is ok with project root name

thanks, all my code is now gone after following your guide

Try to rollback your project files via local history.
right click on your project name and choose local history, find the point that you need and rollback

I tried something that worked for me:
got File -> open project and select the android sub folder of your flutter project.

Your project will oad and you will have a pop up that tells you to update the Gradle plugin, click on Update.

In Android Studio click on the Tools -> SDK Manager -> SDK Tools menu and verify that you have selected the Google Play Services option. In case the box is empty, they click on it and then install it.

Go for the android folder then the app folder inside it and open the gradle.build file, search for the property compileSdkVersion and change the value to 28.

Open the gradle.properties file and add the following lines:
android.useAndroidX=true
android.enableJetifier=true

Then in the file tree on the left panel, at the top change the Android mode by Project, right click on the android folder and select the Migrate to AndroidX option under Refactor. A window appears to inform you that it will make a backup if we want, then click the Migrate button.

Execute flutter clean after it.

It worked for me I hope it will for you !

Updating Android Studio to the new version (3.5) brought this problem to me. Tried all the solutions, but none of them were effective... Any news?
