我无法找到一种方法来创建一个输入字段颤振，将打开一个数字键盘，应该采取数字输入。这是可能的颤振材料部件?一些GitHub讨论似乎表明这是一个受支持的功能，但我无法找到任何关于它的文档。

以下是Flutter中实际手机键盘的代码:
//Mobile
const TextField(
keyboardType: TextInputType.number,
decoration: InputDecoration(
prefixIcon: Icon(Icons.phone), hintText: 'Mobile'),
),

你可以指定数字为keyboardType的TextField使用:
keyboardType: TextInputType.number
检查一下我的总管。飞镖文件
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
// TODO: implement build
return new MaterialApp(
home: new HomePage(),
theme: new ThemeData(primarySwatch: Colors.blue),
);
}
}
class HomePage extends StatefulWidget {
@override
State<StatefulWidget> createState() {
return new HomePageState();
}
}
class HomePageState extends State<HomePage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
backgroundColor: Colors.white,
body: new Container(
padding: const EdgeInsets.all(40.0),
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new TextField(
decoration: new InputDecoration(labelText: "Enter your number"),
keyboardType: TextInputType.number,
inputFormatters: <TextInputFormatter>[
FilteringTextInputFormatter.digitsOnly
], // Only numbers can be entered
),
],
)),
);
}
}
TextField小部件需要设置keyboardType: 和inputFormatters: <TextInputFormatter>[FilteringTextInputFormatter。digitsOnly]只接受数字作为输入。
TextField(
keyboardType: TextInputType.number,
inputFormatters: <TextInputFormatter>[
FilteringTextInputFormatter.digitsOnly
], // Only numbers can be entered
),
在DartPad中的例子
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: HomePage(),
theme: ThemeData(primarySwatch: Colors.blue),
);
}
}
class HomePage extends StatefulWidget {
@override
State<StatefulWidget> createState() {
return HomePageState();
}
}
class HomePageState extends State<HomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: Container(
padding: const EdgeInsets.all(40.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text("This Input accepts Numbers only"),
SizedBox(height: 20),
TextField(
decoration: InputDecoration(
focusedBorder: OutlineInputBorder(
borderSide:
BorderSide(color: Colors.greenAccent, width: 5.0),
),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: Colors.red, width: 5.0),
),
hintText: 'Mobile Number',
),
keyboardType: TextInputType.number,
inputFormatters: <TextInputFormatter>[
FilteringTextInputFormatter.digitsOnly
], // Only numbers can be entered
),
SizedBox(height: 20),
Text("You can test be Typing"),
],
)),
);
}
}
仅限号码类型
keyboardType: TextInputType.number
和更多的选择与数字垫
keyboardType: TextInputType.numberWithOptions(decimal: true,signed: false)
下面是数字键盘的代码: keyboardType: TextInputType。当你在文本框中添加这个代码时，它将打开数字键盘。
final _mobileFocus = new FocusNode();
final _mobile = TextEditingController();
TextFormField(
controller: _mobile,
focusNode: _mobileFocus,
maxLength: 10,
keyboardType: TextInputType.phone,
decoration: new InputDecoration(
counterText: "",
counterStyle: TextStyle(fontSize: 0),
hintText: "Mobile",
border: InputBorder.none,
hintStyle: TextStyle(
color: Colors.black,
fontSize: 15.0.
),
),
style: new TextStyle(
color: Colors.black,
fontSize: 15.0,
),
);
