Use React Native in a Flutter app.
This demo app shows how you can embed React Native in Flutter. It saves a flag to determine which one should be shown on startup. You can toggle between Flutter and React Native by tapp9ng the button in the top right corner.
This is a POC of my WoWs Info app. I am working on a full Flutter rework which contains major UI changes. For better or worse, my users won't like it. That's why I had this idea of asking my users to pick which one their prefer. Slowly after a few updates, I will remove the old React Native app so this is like a transition to Flutter.
You will need to setup both Flutter and React Native environment to run this app. Once you have them setup, you can run it like you run a normal Flutter app with flutter run. However, you need to run npx yarn start to host the React Native app while debugging.
There is one additional step while building the app for release. You need to run npx yarn build-android to build the bundle. The app can still run without it, but it will crash whenever you switch to React Native.
