Unable to Run flutter application in Android Virtual Device on Ubuntu Linux

1.Unable to Run flutter application in Android Virtual Device on Ubuntu Linux
2. AVD is working fine
3. Debugging in Chrome Browser is working correctly
4. I have installed Android Studio via Jet brains Toolbox, so flutter doesn't recognise that, but I don't have any issues with it as I use VS Code for Code Editing

Hi @SubhanRaj
This usually happens when you've unfinished Gradle download (common when Gradle download gets canceled due to network issues or canceled by user) or corrupted Gradle.

To fix the issue you need to first delete the existing Gradle cache and download it again
cd ~
rm -rf .gradle
then run your app, this will take sometime since this is downloading Gradle again, builds will be faster after this
Thank you

[SubhanRaj]

I used the official Gradle installation method given here https://gradle.org/install/

And then added it to path permanently using the following method

• Run the command
  gedit ~/.profile
• Add the line
  export PATH=$PATH:/opt/gradle/gradle-7.0.2/bin
  to the bottom and save
• Log out and log in again

Now gradle -v gives the following output

------------------------------------------------------------ Gradle 7.0.2 ------------------------------------------------------------

Build time: 2021-05-14 12:02:31 UTC
Revision: 1ef1b260d39daacbf9357f9d8594a8a743e2152e

and after trying to run using F5 now it only shows

@SubhanRaj
Please use the supported Gradle version, you don't have to install it manually, clear your Gradle cache, simply run your app. Flutter will fetch supported Gradle.
If the issue persists with supported Gradle, please provide complete reproducible steps
Thank you

[SubhanRaj]

It's working now, I removed manually installed Gradle, updated my JDK and then allowed Android studio to download the gradle itself, after that now it's running fine.

Thanks, @TahaTesser and @FlutterIssues
