TextFormField not showing keyboard when tapped on Android #21370
Description
I'm adding Flutter to an existing Android project and the basic setup is this, I have a FlutterView as the content view of a fragment that sits inside the content area of a native Android DrawerLayout.
My FlutterView has a form with a TextFormField which refuses to show the keyboard when tapped.
I've traced the code down to the io.flutter.plugin.editing.TextInputPlugin and the method call TextInput.show is being reached however the call to android.view.inputmethod.InputMethodManager.showSoftInput(View view, int flags) seems to not be successful because for whatever reason the flutter view is not focused at that time so the Android framework is rejecting the show request.
