Flutter Clean Recursive - Clear up space on your hard drive by cleaning your Flutter projects. This script searches for all Flutter projects in this directory and all subdirectories and runs 'flutter clean'. Note: may take a long time for folders with large amounts of projects.
#!/bin/sh
# To run, download the script or copy the code to a '.sh' file (for example 'fluttercleanrecursive.sh') and run like any other script:
# sh ./fluttercleanrecursive.sh
# or
# sudo sh fluttercleanrecursive.sh

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

  1. List All System Images Available for Download: sdkmanager --list | grep system-images

  2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"
