在做屏幕适配是引入flutter_screenutil库，初始化使用时一直报错，原因是引入的库类名相同解决方法：随便选一个库添加别名flustars库使用如下：查看类冲突原因：1.进入flustars库发现有ScreenUtil类了2.再进入flutter_screenutil库...

解决方法：pubspec.yaml引入dio_cookie_manager: ^1.0.0地址：https://pub.flutter-io.cn/packages/dio_cookie_manager#-installing-tab-

1.新建的images文件夹要与pubspec.yaml同级2.好像出现这条线才行，距离左边两个空格

方法一：修改android模块下的bulid.gradle：添加：maven{ url 'https://maven.aliyun.com/repository/google' }maven{ url 'https://maven.aliyun.com/repository/jcenter' }maven{url 'http://maven.aliyun.com/nexus/...

1.新建flutter项目时，连着安卓手机也不显示设备2.依次打开GeneratedPluginRegistrant文件，点击setup SDK3.选择api即可4.完成
