Flutter TextEditingController无法在键盘上方滚动 [英] Flutter TextEditingController does not scroll above keyboard

问题描述

在android版本中，Flutter TextEditingController不会像在开始输入字段时默认文本字段那样在键盘上方滚动.我试图查看flutter示例目录中提供的示例应用程序，但即使没有TextEditController此类行为的示例.

In android version, Flutter TextEditingController does not scroll above keyboard like default text fields do when you start typing in field. I tried to look in sample apps provided in flutter example directory, but even there are no example of TextEditController with such behaviour.

有什么方法可以实现吗?

Is there any way to implement this.

谢谢.

I found complete working solution here: here

仅使用scroll或focusNode.listner的问题是，仅当我第一次关注文本框时它才起作用，但是如果我最小化键盘并再次单击已经具有焦点的同一个文本框，则listner回调为未触发，因此自动滚动代码未运行.解决方案是在状态类中添加"WidgetsBindingObserver"，并覆盖"didChangeMetrics"功能.

Issue with just using scroll or focusNode.listner is, it was working only if I focus on textbox for the first time, but if I minimize the keyboard and again click on same text box which already had focus, the listner callback was not firing, so the auto scroll code was not running. Solution was to add "WidgetsBindingObserver" to state class and override "didChangeMetrics" function.

希望这可以帮助其他人使Flutter表单更加用户友好.
