I have configured flutter on my Linux Mint and I have downloaded the android command line tools instead of Android Studio. I have also updated the gradle and commandline-tools path on my Linux Mint. Now I want to install the app on my android smartphone and test. How can I do that?

  1. Run Flutter doctor -v to check for any issues (You may have to accept android-licences with flutter doctor --android-licenses).

  2. Connect your android device (Debugging mode should be enabled in the developer options) with USB

  3. You can see connected device in VSCode at bottom-right corner,select your device

  4. Press F5 to run or use "Flutter run" command

You can type this in your terminal in your project directory to get the release apk for your project

 flutter build apk --release

The release apk file will be in build>app>outputs>flutter-apk>app-release.apk

If you want to debug the app, then you can connect your android phone to your pc and then run this command in the terminal:

flutter run

and then select your android device from the options to debug your app
