WeChat Not Installed on iOS?

if you have installed WeChat on your iPhone but you still catch an exception called "wechat not installed",just add the following code to your info.plist:

<key>LSApplicationQueriesSchemes</key>
<array>
<string>weixin</string>
</array>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

Can't Launch WeChat on Android?

Check your signature please.

Failed to notify project evalution listener

Failed to notify project evalution listener

Can't receive response after upgrading to 1.0.0 on iOS

There's no need to override AppDelegate since fluwx 1.0.0. If you have did thad before, please remove the following code in your AppDelegate:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  return [WXApi handleOpenURL:url delegate:[FluwxResponseHandler defaultManager]];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
  return [WXApi handleOpenURL:url delegate:[FluwxResponseHandler defaultManager]];
}

If you have to override these two functions,make sure you have called the super:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    
  return [super application:application openURL:url sourceApplication:sourceApplication annotation:annotation];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
    
  return [super application:application openURL:url options:options];
}

！！！！请先看文档，再看常见Q&A，再查看issue，自我排查错误，方便你我他。依然无法解决的问题可以加群提问， QQ Group：892398530。！！！！

常见Q&A

Fluwx调起失败？

请检查APPID、包名、以及App签名是否一致。debug 和release的签名默认不一样，请注意。

Android Flutter编译失败

1、检查Kotlin版本，打开build.gradle文件，查看以下配置

buildscript {
	······
	ext.kotlin_version = '1.3.11'
	······
}

确保项目中使用的Kotlin版本符合要求； 2、检查Android目录下build.gradle文件中gradle插件版本：classpath 'com.android.tools.build:gradle:3.2.1'和gradle-wrapper.properties文件中的gradle版本是否匹配：distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip，两者的匹配规则见Android官网：Update Gradle

WeChat Not Installed on iOS?

iOS 9系统策略更新，限制了http协议的访问，此外应用需要在“Info.plist”中将要使用的URL Schemes列为白名单，才可正常检查其他应用是否安装。 受此影响，当你的应用在iOS 9中需要使用微信SDK的相关能力（分享、收藏、支付、登录等）时，需要在“Info.plist”里增加如下代码：

<key>LSApplicationQueriesSchemes</key>
<array>
<string>weixin</string>
</array>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

如果没有安装微信，微信登录不了，导致iOS审核失败

fluwx提供了检查用户是否安装微信的方法：isWeChatInstalled()，iOS使用微信相关功能前，务必先检查微信是否安装。

Failed to notify project evalution listener

Failed to notify project evalution listener

isWeChatInstalled返回false

请查看该 issue ，检查AppDelegate中配置是否正确。

Kotlin报错：XXX is only available since Kotlin 1.3 and cannot be used in Kotlin 1.2

1、请检查IDE安装的Kotlin插件版本是否符合fluwx要求：AS打开设置-->Plugin-->Koltin查看插件版本； 2、请检查项目中使用的Kotlin版本：打开build.gradle文件，查看以下配置

buildscript {
	······
	ext.kotlin_version = '1.3.11'
	······
}

listen监听多次调用

请查看该 issue 。这个问题是由于listen被多次注册导致的，使用者自己代码的问题，非fluwx导致的，请在合适的时机将listen cancel掉：

StreamSubscription<WeChatAuthResponse> _wxlogin;
_wxlogin = fluwx.responseFromAuth.listen((val) {})
@override
  void dispose() {
	_wxlogin.cancel();
}

分享完成或者取消分享后App崩溃

如果你手动注册了WXEntryActivityandWXPayEntryActivity，请检查Manifest中包名是否写对了。

IOS编译错误：No such module 'fluwx'

如果项目本身是在Android环境配置的，移到iOS的环境的时候，会出现该问题，请按照正常步骤配置。

支付成功后，按物理按键或手机自动返回商户APP，监听不到返回数据

有人反应会出现fluwx.responseFromPayment.listen监听无效，无法获取支付结果，建议可以直接向服务器查询是否成功。

iOS报错：Specs satisfying the fluwx (from .symlinks/plugins/fluwx/ios) dependency were found, but they required a higher minimum deployment target.

请在在pod file里将iOS项目deployment target改到9.0。

ResponseType与Dio插件中的命名冲突

使用as的方式导包即可：import 'package:fluwx/fluwx.dart' as fluwx;
