最近开发过程中flutter_spinkit这个拥有多种种风格加载指示器 一、flutter_spinkit
引入flutter_spinkit # 多种风格的模糊进度指示器flutter_spinkit: ^5.1.0效果示例
const spinkit SpinKitRotatingCircle(color: Colors.white,size: 50.0,
);final spinkit SpinKitFadingCircle(itemBuilder: (BuildContext context, int index) {return DecoratedBox(decoration: BoxDecoration(color: index.isEven ? Colors.red : Colors.green,),);},
);final spinkit SpinKitSquareCircle(color: Colors.white,size: 50.0,controller: AnimationController(vsync: this, duration: const Duration(milliseconds: 1200)),
);二、实现指示器效果
代码如下
import package:flutter/material.dart;
import package:flutter_spinkit/flutter_spinkit.dart;/// 加载中
class LoadingWidget extends StatelessWidget {const LoadingWidget({this.bgColor, Key? key}) : super(key: key);final Color? bgColor;Color getColorAtIndex(int index) {if (index 0) {return Colors.deepOrangeAccent;}if (index 1) {return Colors.redAccent;}if (index 1) {return Colors.lightBlueAccent;}return Colors.white70;}overrideWidget build(BuildContext context) {return Container(color: bgColor ! null ? bgColor : Colors.white,child: Center(child: Column(mainAxisAlignment: MainAxisAlignment.center,crossAxisAlignment: CrossAxisAlignment.center,children: [SizedBox(width: 300.0,height: 60.0,child: SpinKitThreeBounce(size: 40.0,itemBuilder: (BuildContext context, int index) {return DecoratedBox(decoration: BoxDecoration(color: getColorAtIndex(index),shape: BoxShape.circle));},),),Padding(padding: const EdgeInsets.only(top: 20)),Text(//S.of(context).viewStateLoading,正在加载中一会就到了,style: TextStyle(fontSize: 18,fontWeight: FontWeight.w500,fontStyle: FontStyle.normal,color: Colors.white,decoration: TextDecoration.none,),)],),),);}
