Вот мой код. Теперь я хочу, чтобы при нажатии кнопки «Повышенная кнопка» в текстовое поле отображалось то число, которое помечено на кнопке. Как вы можете видеть, у меня есть два текстовых поля, также мне нужно сделать их выбираемыми. Когда вы нажимаете на текстовое поле, вы фокусируете их и можете ввести номер.

Приложение представляет собой калькулятор очков для карточной игры, показанной здесь.

Это простой пример, чтобы получить Button текст TextField !Измените его в соответствии с вашими требованиями.

объявить TextEditingController s:

 TextEditingController cont1 = TextEditingController(),
      cont2 = TextEditingController();
 

И способ сборки:

 @override
  Widget build(BuildContext context) {
    return Column(children: [
      Row(
        children: [
        Expanded(
          child: TextField(
            controller: cont1,
            //other params
          ),
        ),
          const Spacer(flex: 1),
        Expanded(
          child: TextField(
            controller: cont2,
            //other params
          ),
        ),
      ]),
      ElevatedButton(
          onPressed: () {
            setState((){ //or other state management
              cont1.text = "8";
            });
          },
          style: ElevatedButton.styleFrom(
              padding: const EdgeInsets.only(
                  top: 20, bottom: 20, right: 50, left: 50)),
          child: const Text('8', style: TextStyle(color: Colors.white))),
    ]);
  }
