# flutter_rich_input 不再维护，使用了更好的方式，新启动了一个新的 rich_input 插件，[点击这里查看](https://pub.dev/packages/rich_input)
这是一个高性能的富媒体输入框，通过原生的 textfield 扩展实现，具有较小的破坏性，同时具有较强的扩展性，实现了@某人，#话题，表情等功能，支持自定义高亮
文档语言: [English](README.md) | [中文简体](README-ZH.md)
## 特色功能
- 用较少的代码，尽量使用原生的 textfield 能力，减少破坏性及后续兼容性
- 支持@某人 #话题 插入表情等
- 支持自定义高亮效果，甚至实现自己的渲染方式
- 支持自定义 value 字段，增强富文本的能力
## 开始入门
```dart
import 'package:flutter/material.dart';
import 'package:flutter_rich_input/block/rich_block.dart';
import 'package:flutter_rich_input/flutter_rich_input.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State {
RichInput _richInput;
FocusNode _focusNode;
@override
void initState() {
_focusNode = FocusNode();
_richInput = RichInput();
// refresh text and value
_richInput.controller.addListener(() {
setState(() {});
});
_richInput.addText("text");
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Padding(
padding: const EdgeInsets.all(15),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
_richInput.textField(focusNode: _focusNode),
Wrap(
spacing: 10,
children: [
RaisedButton(
onPressed: () {
_richInput.addText("text");
},
child: const Text("Add Text"),
),
RaisedButton(
onPressed: () {
_richInput.addText("😁");
},
child: const Text("Add 😁"),
),
RaisedButton(
onPressed: () {
_richInput.addText("👍");
},
child: const Text("Add 👍"),
),
RaisedButton(
onPressed: () {
final at = RichBlock(text: " @abc ", value: " @123456 ");
_richInput.addBlock(at);
},
child: const Text("Add @ "),
),
RaisedButton(
onPressed: () {
final at = RichBlock(
text: " #subject ",
value: " #888999 ",
style: const TextStyle(
color: Colors.red,
fontWeight: FontWeight.bold,
),
);
_richInput.addBlock(at);
},
child: const Text("Add #"),
),
RaisedButton(
onPressed: () {
_richInput.clear();
},
child: const Text("Clear"),
),
RaisedButton(
onPressed: () {
_focusNode.unfocus();
},
child: const Text("unfocus"),
)
],
),
const SizedBox(height: 10),
Text("Text:${_richInput.text}"),
const SizedBox(height: 10),
Text("Value:${_richInput.value}"),
],
),
),
),
);
}
}
```
> 主要通过 RichInput 提供额外的 api，通过 RichInput.textfield 提供和原生 textfield 一致化的接口
