══╡ 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#80af0(logicalKey: LogicalKeyboardKey#00106(keyId: "0x200000106", keyLabel: "Meta Left", debugName: "Meta Left"), physicalKey: PhysicalKeyboardKey#700e3(usbHidUsage: "0x000700e3", debugName: "Meta Left")) and its data: RawKeyEventDataLinux#ef142(toolkit: GTK, unicodeScalarValues: 0, scanCode: 133, keyCode: 65511, modifiers: 0, isDown: true) 'package:flutter/src/services/raw_keyboard.dart': Failed assertion: line 694 pos 7: '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: https://github.com/flutter/flutter/issues/new?template=2_bug.md

'Menu' keycode is 0X85 on TV device. {0x00000085, 65511}, // LogicalKeyboardKey.metaLeft

Do you want to capture the menu button in your app or can you simply ignore it? In the latter case we can just remove the mapping from key_event_channel.cc.

I think we can ignore this issue for now, because it doesn't affect app development.
