What can be the reason for getting this log output - Lost connection to device - when executing flutter run?

Question

• Why is the device getting disconnected with the log stating - Lost connection to device - after excuting flutter run?
  
• Everything works fine till the login screen, where the user is able to correctly login using google Sign in, but the next 'HOME' screen, as it starts loading, breaks & I receive the following log, as a preceding to the lost connection to device - statement.

Lost connection to device.

Solution

I got a very similar error and solved it as follows:

1. Remove the emulator app or your physical device
2. Close the emulator or restart the physical device
3. Execute the flutter clean command
4. Close the IDE (in my case Intellij)
5. Open the project again and run your app.

NOTE: The above worked for iOS where I got the error of Lost connection to device

I already tried this with my Windows + android setup, but didn't help.

As a side-note, this does not answer the question.
