问题描述
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Todo Add'),centerTitle: true,),body: Container(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 12,vertical: 10),child: Column(
children: [
TextField(
controller: controller,onChanged: (value) => title = value,decoration: Inputdecoration(hintText: 'Enter your title'),SizedBox(
height: 10,TextField(
controller: controller1,onChanged: (val) => body = val,decoration: Inputdecoration(hintText: 'Enter your body'),SizedBox(
height: 40,ElevatedButton(
onpressed: () {
setText();
},child: Text("Submit"),Text(
'Title : $text',style: TextStyle(fontSize: 16),SizedBox(height: 10,Text(
'Body : $desc',],);
}
解决方法
您可以使用控制器获取 TextField 的文本。
String textfield1 = controller.text;
并将这个变量像参数一样发送到另一个屏幕
Navigator.pushNamed(
context,route,arguments: [controller.text,controller1.text]
);
并在另一个屏幕中获取此参数
final args = ModalRoute.of(context).settings.arguments;
