Flutter is a framework which will help you make apps. It is currently owned by Google. It uses Dart language to create awesome apps and has support for Windows, Mac and Linux. Some see it as a very simple method to create mobile apps. Which could be true as well considering how they treat elements as widgets and focus on them.

I have considered it using once. But it changed hands at that time. Google bought it from someone else. There was confusion regarding how it will be treated and how old accounts will be managed. My own Flutter account got removed as a part of revamp ( IIRC ).
I see. It looks so easy to use. Mostly like Bootstrap. Also, it is from Google. I will check whether there is any integration wit Android Studio available.
I saw an installation guide for Flutter which had some mention of Android Studio. I didn't dig much though.
