有没有办法将自定义工具栏放在键盘上?
Is there any way to put custom toolbar on the keypad?
我想在键盘上放置一个自定义工具栏,如上图所示。颤振有可能吗?或者我应该在 iOS 或 Android 端编写代码?
是的,在 flutter 中有一种方法可以实现这一点。
- 创建要添加的工具栏的小部件。
- 将其设置为在输入焦点上可见。
为了参考,我正在分享我是如何实现的代码。
class InputDoneView extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Container(
width: double.infinity,
color: Style.lightGrey,
child: Align(
alignment: Alignment.topRight,
child: Padding(
padding: const EdgeInsets.only(top: 1.0, bottom: 1.0),
child: CupertinoButton(
padding: EdgeInsets.only(right: 24.0, top: 2.0, bottom: 2.0),
onPressed: () {
FocusScope.of(context).requestFocus(new FocusNode());
},
child: Text(
"Done",
style: TextStyle(color: Style.primaryColor,fontWeight: FontWeight.normal)
),
),
),
),
);
}
}
当输入字段聚焦和聚焦时在主视图中调用它。
showOverlay(BuildContext context) {
if (overlayEntry != null) return;
OverlayState overlayState = Overlay.of(context);
overlayEntry = OverlayEntry(builder: (context) {
return Positioned(
bottom: MediaQuery.of(context).viewInsets.bottom, right: 0.0, left: 0.0, child: InputDoneView());
});
overlayState.insert(overlayEntry);
}
removeOverlay() {
if (overlayEntry != null) {
overlayEntry.remove();
overlayEntry = null;
}
}
