Question

通常，如果我们按“后退”按钮，键盘将隐藏，但是如本视频所示，当反复按“后退”按钮时，键盘不会被隐藏。但是在Android 7上的测试中，当我按下隐藏的键盘后退按钮时，它运行良好。

这是我的输入代码

TextFormField(
  validator: (e) {
    var message;
    if (e.isEmpty) {
      message = emailEmpty;
    }
    return message;
  },
  onSaved: (e) => email = e,
  decoration: InputDecoration(
    prefixIcon: Icon(
      Icons.email,
      color: Color(0xFF003d64),
    ),
    labelText: emailInput,
  ),
),

flutter doctor -v

尝试将dispose方法添加到您的类State（窗口小部件）：

    @override
      void dispose() {
        // TODO: implement dispose
        super.dispose();
      }

按下颤振后退按钮，不会在Android 10上隐藏键盘
