Error output

The exception I got when I typed several k characters into a textfield, this only occured when I am in windows (not on linux) and it only occured with only k key (US-keyboard):

══╡ EXCEPTION CAUGHT BY SERVICES LIBRARY ╞══════════════════════════════════════════════════════════
The following assertion was thrown during a platform message callback:
Attempted to send a key down event when no keys are in keysPressed. This state can occur if the key
event being sent doesn't properly set its modifier flags. This was the event:
RawKeyDownEvent#b7622(logicalKey: LogicalKeyboardKey#0006b(keyId: "0x0000006b", keyLabel: "k",
debugName: "Key K"), physicalKey: PhysicalKeyboardKey#700e0(usbHidUsage: "0x000700e0", debugName:
"Control Left")) and its data: RawKeyEventDataLinux(keyLabel: k, keyCode: 75, scanCode: 37,

'package:flutter/src/services/raw_keyboard.dart':
Failed assertion: line 626 pos 12: 'event is! RawKeyDownEvent || _keysPressed.isNotEmpty'

Either the assertion indicates an error in the framework itself, or we should provide substantially
more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
