Flutter Create Contest

This package is also a submission to Flutter Create contest. The basic rule of this contest is to measure the total Dart file size less or equal 5KB.

After unzipping the compressed file, run following command to update dependencies:

flutter packages get

To evaluate the total size of all Dart files:

find . -name "*.dart" ! -name "*test*"  | xargs cat | wc -c

To evaluate only the package Dart code:

find . -name "*.dart" ! -name "*test*" ! -path "*example*"  | xargs cat | wc -c

To run simple example app with a total size of dart code less or equal 5KB:

cd example
flutter clean
flutter run

Hot restart app with "R" to replay the animation

To run the full example app:

cd example
mv lib/main.dart tmp && mv lib/main.dart.bk lib/main.dart && mv tmp lib/main.dart.bk
flutter clean
flutter run

Using built-in float action buttons to change value and see the effect
