当长文本展开和收缩控件我们需要使用readmore来处理长文本展开和收缩方便阅读 一、引入readmore
在工程的pubspec.yaml中引入插件 readmore: ^2.1.0
ReadMoreText的属性如下
const ReadMoreText(this.data, {Key? key,this.preDataText,this.postDataText,this.preDataTextStyle,this.postDataTextStyle,this.trimExpandedText show less,this.trimCollapsedText read more,this.colorClickableText,this.trimLength 240,this.trimLines 2,this.trimMode TrimMode.Length,this.style,this.textAlign,this.textDirection,this.locale,this.textScaleFactor,this.semanticsLabel,this.moreStyle,this.lessStyle,this.delimiter _kEllipsis ,this.delimiterStyle,this.callback,}) : super(key: key);
二、使用ReadMoreText
在长文本使用展开和收缩显示控件的
ReadMoreText(Flutter is Google’s mobile UI open source framework to build high-quality native (super fast) interfaces for iOS and Android apps with the unified codebase.,trimLines: 2,colorClickableText: Colors.pink,trimMode: TrimMode.Line,trimCollapsedText: Show more,trimExpandedText: Show less,moreStyle: TextStyle(fontSize: 14, fontWeight: FontWeight.bold),),
完整代码如下
import package:flutter/material.dart;
import package:readmore/readmore.dart;class ReadMorePage extends StatefulWidget {const ReadMorePage({super.key});overrideStateReadMorePage createState() _ReadMorePageState();
}class _ReadMorePageState extends StateReadMorePage {overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: const Text(HeroPage),),body: Center(child: ReadMoreText(Flutter is Google’s mobile UI open source framework to build high-quality native (super fast) interfaces for iOS and Android apps with the unified codebase.,trimLines: 2,colorClickableText: Colors.pink,trimMode: TrimMode.Line,trimCollapsedText: Show more,trimExpandedText: Show less,moreStyle: TextStyle(fontSize: 14, fontWeight: FontWeight.bold),),),);}
}
