我们常用的分割线一般有两种.一种是Divider.一种是使用DecoratedBox实现.
第一种：Divider(Double:height,Double:indent,color:color)
官方:
const Divider({ Key key, this.height, this.thickness, this.indent, this.endIndent, this.color, }) : assert(height == null || height >= 0.0), assert(thickness == null || thickness >= 0.0), assert(indent == null || indent >= 0.0), assert(endIndent == null || endIndent >= 0.0), super(key: key);
使用:
Divider(height: 1.0,indent: 35,color: Colors.black,),
第二种：DecoratedBox(decoration:BoxDecoration(Border:border))
一般使用与Container控件中.
官方:
const BoxDecoration({ this.color, this.image, this.border, this.borderRadius, this.boxShadow, this.gradient, this.backgroundBlendMode, this.shape = BoxShape.rectangle, }) : assert(shape != null), assert( backgroundBlendMode == null || color != null || gradient != null, 'backgroundBlendMode applies to BoxDecoration\'s background color or ' 'gradient, but no color or gradient was provided.' );
使用:
decoration: BoxDecoration( border: new Border(top: BorderSide(width: model.linetype == "1" ? 8 : 0,color: Colors.black,style: model.linetype == "1" ? BorderStyle.solid : BorderStyle.none)), color: Color(0xFF363644), ),
应用中实践.一般会有组间分割.以及组内分割.效果如下:
分割应用场景.png
代码如下:
import 'dart:convert' as JSON;
import 'package:flutter/material.dart';
class MinePage extends StatefulWidget {
@override
_MinePageState createState() => _MinePageState();
}
class _MinePageState extends State {
//linetype 1是高的 2是缩头的分割线
//type 0 是有value和箭头 1是只有箭头 2是只有开关 3是只有文本
var jsonText1 = '[{"title": "车辆管理","value": "粤B3232ls","linetype": "1","type": "0"},{"title": "车辆授权","value": "","linetype": "2","type": "1"},{"title": "重置登录密码","value": "","linetype": "1","type": "1"},{"title": "手势密码","value": "1","linetype": "2","type": "2"},{"title": "重置手势密码","value": "","linetype": "2","type": "1"},{"title": "意见反馈","value": "","linetype": "1","type": "1"},{"title": "客服电话","value": "400-10220-1022","linetype": "2","type": "3"},{"title": "救援电话","value": "3202923920","linetype": "2","type": "3"}]';

其中解析模型:从后台获取json数据以后从https://javiercbk.github.io/json_to_dart/中转换即可
