failed to get fis auth token

1.https证书问题，之前请求接口域名证书是dv证书，更换的新域名配置了泛域名证书，导致dio证书验证出错

:DioError [DioErrorType.DEFAULT]: HandshakeException: Handshake error in client (OS Error:
CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:354))

解决办法：dio验证强制返回true：


(_dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (client){
  client.badCertificateCallback = (cert, host, port){
    return true;
  };
};

2.Android 5.0之前的版本（API level < 21）使用Dalvik runtime来执行代码，默认限制每个APK只能使用一个classes.dex文件，而DEX规范又将单个DEX文件内引用的方法总数限制为65536个，第三方引入过多函数超限

D8: Cannot fit requested classes in a single dex file (# methods: 75464 > 65536)

com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

The number of method references in a .dex file cannot exceed 64K. Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html

解决办法：在android/app/build.gradle配置中添加参数：1.defaultConfig内添加 multiDexEnabled true 2.dependencies内添加 implementation 'com.android.support:multidex:1.0.3'

3.集成高德地图插件安卓运行报错闪退：

E/flutter (14718): [ERROR:flutter/shell/platform/android/platform_view_android_jni_impl.cc(43)] java.lang.NoClassDefFoundError: Failed resolution of: Lcom/amap/api/location/AMapLocationClient;

解决办法：在app/build.gradle文件的dependencies配置中添加相关sdk依赖，参考下图：

解决办法：需要配置vpn

5. List赋值问题，有一个map list变量，我用一个新的list变量接收，然后在修改新的list数据的时候发现，旧的list变量的内容也变了：


List list1 = [{'label': 'first name', 'value': 'Jack'}, {'label': 'last name', 'value': 'Gold'}];
List list2 = List.from(list1);
list2.last['valuee'] = 'Gould';
print('list1: $list1 \n list2: $list2');
 
// Console
flutter: list1: [{label: first name, value: Jack}, {label: last name, value: Gold, valuee: Gould}]
 list2: [{label: first name, value: Jack}, {label: last name, value: Gold, valuee: Gould}]

解决方案：

通过for循环方式添加：List list2; for (var item in list1) {list2.add(item);}

通过json decode+encode组合：List list2 = List.from(json.decode(json.encode(list1)));

6. iOS端 Pod Install报错：[!] Invalid `Podfile` file: undefined method `exists?' for File:Class.

原因是ruby3.2删除了对 exists 的支持导致该问题

解决方案：

1）升级Flutter SDK

2）打开flutter目录下的这个文件：/flutter/packages/flutter_tools/bin/podhelper.rb，搜索到这一行内容：return [] unless File.exists? file_path 将其中的 exists 改为 exist

后续问题会持续补充...
