My first Hello World Flutter app is an easy-to-use tally counter with multiple color counters. Count people, sheep, kisses, or smiles, and nobody will know what you are counting! Increase, decrease, reset the counters, or share them with other apps.
It may very well be the simplest Android app. Works even on Android 1.0! All it does is display the famous Hello World! text in a toast - the familiar Android small popup used to show quick messages to the user. Then the app closes, even before starting... :-)
A Flutter test app that you can run in your browser to generate dozens or hundreds of attractive random colors. You can select options to influence the type of color it produces and copy the colors to the clipboard for reuse in other apps or places.
