Make sure command line tools and NDK are installed. For NDK:

In your Android Studio, Go to File -> Project Structure -> SDK Location -> Under "Android NDK Location", click on "Download" Android NDK

Then set flutter's config:

flutter config --android-sdk="/home/user/Android/Sdk"
flutter config --android-studio-dir="/usr/local/android-studio"
