Explode Animation #

A Flutter package to create widgets with exploding animation. Currently two types of animations are supported. More will be added in future. Pull Requests are welcome.

Note : If you don't provide a list of colors then the PalleteGenerator package will be used which may take a lot of time to extract colors from a high resolution image.

Installation #

First, add explosion_animation as a dependency in your pubspec.yaml file.

No configuration required - the plugin should work out of the box.
