Github cloned projects could'nt be run.

[JosephVoid]

Whenever i try to run cloned projects from Github....It says "Running gradle task 'assembleDebug'.." and stays like that forever.But when i create new flutter projects and copy your code it works...any ideas on what could be the problem.

@JosephVoid actually this happened with me too ,
first time i opened pubspec.yaml and make pub get but it hangs on Running gradle task
you should run Pub upgrade then build again

I'm having the same issue. The cloned projects from GIT didn't run at all, infact it doesn't detect dependencies too when I click on get dependencies. Why am I facing this, kindly help?

[deepakDOTexe]

I am a newbie to android studio so I don't know exactly what the problem was, but in my android/gradle/build.gradle file of the cloned project I edited the following line

classpath 'com.android.tools.build:gradle:3.5.3'

to

classpath 'com.android.tools.build:gradle:3.5.0'

which was similar to the projects created by me offline. This might be due to running an older version of this gradle stuff on my machine. I am not sure but it worked for me for the time being.

You can try running with flutter run command with a verbose flag.

1. It's because Gradle cannot be downloaded because you haven't added Android Studio to Windows Firewall exceptions.
2. It's the migration problem for which you can make similar changes as I have suggested here: Upgrading pre 1.12 Android projects mi_card_flutter#28

After doing these two things, I am able to run all of the projects. Hope this helps!

Go to file>Project Structure>and see project SDK most of the time it is not set set it.
Copy the SDF from SDK manager from top right of your android studio window.
