解决方法
您可以通过使用
viewInsets检查键盘可见性并基于它隐藏fab来实现它.
例：
import 'package:flutter/material.dart';
void main() {
runApp(new MaterialApp(
title: "Example",home: new FabHideOnKeyboard(),));
}
class FabHideOnKeyboard extends StatefulWidget {
@override
_FabHideOnKeyboardState createState() => new _FabHideOnKeyboardState();
}
class _FabHideOnKeyboardState extends State<FabHideOnKeyboard> {
@override
Widget build(BuildContext context) {
final bool showFab = MediaQuery.of(context).viewInsets.bottom==0.0;
return Scaffold(
resizeToAvoidBottomPadding: true,body:Container(
alignment: Alignment.center,child: Column(
mainAxisAlignment: MainAxisAlignment.center,children: <Widget>[
Text("TextField:"),TextField()
],),floatingActionButton: showFab?Icon(Icons.add):null,);
}
}
希望有所帮助！
