I just wanted to mention that adb and other tools are available now from google
without needing to download the very large android studio.
Linux size of the zip file is 3.4MB
But am getting an issue with flutter via the command line,
this is not a real issue for me as I have/can down load Android studio.
If all components required by flutter are in Platform-Tools,
it would be cool if flutter could work without android studio download.
flutter run
"Unable to locate a development device; please run 'flutter doctor' for information about installing additional components."
with zip file extracted to /home/myhomedir/platform-tools/
flutter doctor say
[-] Android toolchain - develop for Android devices
• Android SDK at /home/myhomedir
• Try re-installing or updating your Android SDK.
Thanks
