Error launching application on Redmi Note 4.

Earlier it was Error waiting for a debug connection: Bad state: No element, I switched to master from stable and now it is throwing this error on run. App is getting installed but crashing by throwing this error.

You need to execute flutter clean command in your project and also make sure the device properly connected, the cable is attached properly. Also, you have to allow permission to launch on an app device and you should see a dialog while launching the app and restart the device...

$ flutter clean
