fix: writeText action only writing one character on iOS and Android

[k-ane]

I've only tested on iOS and Android simulator, but in both cases write text would only write one character, this was using the example provided by Fluttium as well.

The way I was able to work around this for now was to duplicate the action and write the whole text in one go instead of letter by letter, but a better solution should be found.

@override
  Future<bool> execute(Tester tester) async {
    TextInput.setInputControl(_textInputController);
    tester.emitPlatformMessage(
      SystemChannels.textInput.name,
      SystemChannels.textInput.codec.encodeMethodCall(
        const MethodCall('TextInputClient.requestExistingInputState'),
      ),
    );
    TextInput.restorePlatformInputControl();

    // Temporary workaround, enter whole text instead of character by character
    await _enterText(tester, text);
    await tester.pumpAndSettle();

    // for (final char in text.split('')) {
    //   await _enterText(tester, char);
    //   await tester.pumpAndSettle();
    // }
    return true;
  }
