Flutter文本输入插件regular_textfield的使用
regular_textfield
包允许你在你的 Flutter 应用程序中添加一个带有嵌入式标题和文本字段的简单美观的文本字段。
开始使用
- 在
pubspec.yaml
文件中添加最新版本的包(并运行dart pub get
):
dependencies:
regular_textfield: ^0.0.3
- 导入包并在 Flutter 应用程序中使用它:
import 'package:regular_textfield/regular_textfield.dart';
示例
你可以修改许多属性,例如:
title
hintText
TextEditingController
suffix
prefixText
isPrefix
isTitle
isPrefixIcon
path
radius
fontSize
fieldColor
isReadOnly
validator
textInputAction
keyboardType
maxline
minLine
onchanged
示例代码
以下是一个完整的示例代码,展示了如何在应用中使用 regular_textfield
包:
import 'package:flutter/material.dart';
import 'package:regular_textfield/regular_textfield.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return new MaterialApp(
title: '文本输入插件示例',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new TextFieldScreen(),
);
}
}
class TextFieldScreen extends StatefulWidget {
const TextFieldScreen({Key? key}) : super(key: key);
[@override](/user/override)
State<TextFieldScreen> createState() => _TextFieldScreenState();
}
class _TextFieldScreenState extends State<TextFieldScreen> {
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
SizedBox(
height: 50,
),
RegularTextFormFeild(
title: '姓名',
hintText: "请输入您的姓名",
controller: TextEditingController(),
fieldColor: Colors.grey.shade200,

regular_textfield
并不是 Flutter 官方提供的插件或组件,可能是某个第三方库或自定义组件。如果你正在使用某个特定的第三方库,建议查看该库的文档以了解如何使用 regular_textfield
。
不过,我可以为你提供一个类似的自定义 RegularTextField
组件的实现示例,以及如何在 Flutter 中使用它。
自定义 RegularTextField
示例
import 'package:flutter/material.dart';
class RegularTextField extends StatelessWidget {
final String hintText;
final TextEditingController? controller;
final ValueChanged<String>? onChanged;
final bool obscureText;
final int maxLines;
final TextInputType? keyboardType;
const RegularTextField({
Key? key,
required this.hintText,
this.controller,
this.onChanged,
this.obscureText = false,
this.maxLines = 1,
this.keyboardType,
}) : super(key: key);
[@override](/user/override)
Widget build(BuildContext context) {
return TextField(
controller: controller,
onChanged: onChanged,
obscureText: obscureText,
maxLines: maxLines,
keyboardType: keyboardType,
decoration: InputDecoration(
hintText: hintText,
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(8.0),
),
contentPadding: const EdgeInsets.symmetric(horizontal: 12.0, vertical: 14.0),
),
);
}
}
在 Flutter 中使用 RegularTextField
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('RegularTextField Example'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
children: [
RegularTextField(
hintText: 'Enter your email',
onChanged: (value) {
print('Email: $value');
},
),
SizedBox(height: 16.0),
RegularTextField(
hintText: 'Enter your password',
obscureText: true,
onChanged: (value) {
print('Password: $value');
},
),
],
),
),
),
);
}
}
