颤振的屏幕键盘未显示字符

Question

从最近开始，在运行（或调试）Flutter应用程序时，我开始收到屏幕键盘损坏的消息。

从https://flutter.dev/docs/cookbook/forms/validation运行表单验证演示，请参阅所附的屏幕截图。 键盘实际上接受按键。奇怪的是，切换到大写字母会使键盘显示（大写）字符。我应该重新卸载/安装堆栈还是其他合适的措施？

Answer 1

转到android studio-> avd管理器->您的模拟器->擦除数据，然后重试。如果无法解决，请删除该模拟器并创建一个新的模拟器。

Answer 2

尝试冷启动模拟器。这对我有用！
