  UIWidget is a Unity Package which helps developers to create, debug and deploy efficient, cross-platform Apps.

  Project mention: Flutter + Unity/UnreLEngine or others | reddit.com/r/FlutterDev | 2021-01-22

  Unity actually has the UIWidgets package which is based on Flutter. I'd highly recommend sticking to that; even using native Android with Unity is kind of a pain in the ass since you need to export your Unity project and build the project in Android Studio any time you want to test interaction between the UI and the game.
