解决方式，在Flutter安装位置C:\flutter\packages\flutter_tools\gradle，flutter.gradle中修改添加如下内容。
buildscript {
repositories {
//google()
mavenCentral()
google()
maven { url 'http://download.flutter.io' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }//可以查看下错误提示和阿里云，缺哪个，就补充哪个
maven { url 'https://maven.aliyun.com/repository/google'}
maven { url 'https://maven.aliyun.com/repository/jcenter'}
maven { url 'http://maven.aliyun.com/nexus/content/groups/public'}
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
}
}
allprojects {
repositories {
google()
mavenCentral()
maven { url 'http://download.flutter.io' }
maven { url 'https://maven.aliyun.com/repository/google'}
maven { url 'https://maven.aliyun.com/repository/jcenter'}

从网上下载别人的FLutter 工程 ，有时会出现类似下列的错误，解决方式为删除掉android文件夹，再重新生成一次就好了，这个是由于Java 的版本不一致造成的。

[form_app] flutter pub get
Running "flutter pub get" in form_app...
Because json_serializable >=4.0.0 <4.0.1 depends on analyzer ^0.41.2 and json_serializable ^4.0.1 depends on analyzer >=0.41.2 <2.0.0, json_serializable ^4.0.0 requires analyzer >=0.41.2 <2.0.0.
And because mockito >=5.0.16 depends on analyzer ^2.1.0, mockito >=5.0.16 is incompatible with json_serializable ^4.0.0.
So, because form_app depends on both mockito ^5.0.16 and json_serializable ^4.0.0, version solving failed.
pub get failed (1; So, because form_app depends on both mockito ^5.0.16 and json_serializable ^4.0.0, version solving failed.)
