Rive animations in Flutter

Rive is a very useful animation tool that can create beautiful animations and we can add these in our Application. In flutter, we can add animations by writing so many lines of code but this is not a good practice for a developer. Instead of writing lines of code to create animation, we can create one, using this powerful Rive animation tool. Please read all the below points in sequence to understand the topic clearly.
