Flutter: кнопка внутри позиционированного виджета onPressed() не работает

Я пытаюсь реализовать окно чата, похожее на WhatsApp, с функцией голосового сообщения точно так же, как в WhatsApp, дизайн пользовательского интерфейса для голосового сообщения работает нормально, но кнопка удаления, отправки, паузы внутри позиционированных виджетов не работает (эти кнопки используются при записи аудио с использованием концепции блокировки именно в WhatsApp), когда я нажимаю эти кнопки или внутри позиционированных виджетов, появляется клавиатура для основного окна сообщения. Как я могу избежать этого и заставить кнопки работать при нажатии. ниже мой код;

class _HomePageState extends State<HomePage> with SingleTickerProviderStateMixin {
late AnimationController controller;

@override
void initState() {
    super.initState();
    controller = AnimationController(
    vsync: this,
    duration: const Duration(milliseconds: 600),
    );
}

@override
void dispose() {
    controller.dispose();
    super.dispose();
}

@override
Widget build(BuildContext context) {
    return Scaffold(
    appBar: AppBar(
        title: const Text("Audio Chat"),
    ),
    body: Padding(
        padding: const EdgeInsets.all(Globals.defaultPadding),
        child: Column(
        children: [
            const Expanded(child: AudioList()),
            Row(
            mainAxisSize: MainAxisSize.max,
            children: [
                ChatBox(controller: controller),

ОБНОВЛЯТЬ :

Единственный обходной путь, который я нашел до сих пор, — это заключить виджет timerLocked Positioned с помощью Stack,SizedBox,Positioned, как показано ниже.

    Widget timerLocked() {
return Positioned(
  child: SizedBox(
    height: 80,
    width: timerWidth,
    child: Stack(
      children: [
        Positioned(
        right: 0,
        bottom: 0,
        height: 80,
        width: timerWidth,
        child: Container(
        decoration: BoxDecoration(
          borderRadius: BorderRadius.circular(Globals.borderRadius - 10),
          color: Colors.lightBlue,
        ),
        child: Padding(
          padding: const EdgeInsets.only(left: 15, right: 25),
          child: Column(
            children: [
              
            ],
          ),
        ),),
        ),
      ],),),);
}
