flutte的EditText

TextField相当于Android中的EditText：

TextField(
    decoration: new InputDecoration(hintText: "This is a hint"),// 提示语
 )

获取TextField的值：

= TextEditingController();


TextField(
          controller: _name,// 控制器
          decoration: new InputDecoration(hintText: "This is a hint"),
          onChanged: (value){// 双向绑定
            this.setState(() {
              this._name.text = value;
            });
          },
        ),

示例：

import 'dart:convert';
import 'dart:isolate';
import 'package:dio/dio.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

void main() => runApp(DemoApp());

class DemoApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: '导航演示1',
      home: new MyAppHome(),
    );
  }
}

class MyAppHome extends StatefulWidget {
  @override
  _MyAppHomeState createState() => _MyAppHomeState();
}

class _MyAppHomeState extends State<MyAppHome> {
  TextEditingController _name = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      body: Center(
        child: new TextField(
          controller: _name,
          decoration: new InputDecoration(hintText: "This is a hint"),
          onChanged: (value){
            this.setState(() {
              this._name.text = value;
            });
          },
        ),
      ),
    );
  }
}
