如何在 flutter 中显示默认 Android 消息（如（+）按钮并显示自定义小部件代替键盘？

Question

How can I implement default android Messages like a custom widget in place of the keyboard shown in the GIF?

Answer 1

When you tap on + button, what happens is,

• Keyboard Closed, to achieve this you can use FocusNode instance and assign in TextField , to unfocus or to close keyboard, you can achieve it by focusNode.unfocus() .

• The content you see on tap of + is outside keyboard, ie you have to create widget and change it's visibility accordingly, Visibility can be used.

• In other case misc options is visible and user tap on keyboard icon then change visibility of extra options and obtain focus of FocusNode instance(enable keyboard), by focusNode.requestFocus() .
