Development Setup

Please read DEVELOPMENT.md for development setup.

Preparation

Migrate to V6 now

NOTE: V6 has a lot of breaking changes, especially for iOS, such as supporting scene_delegate and Swift Package Manager. Please read the document carefully before migrating to V6.

Fluwx is good but not God. You'd better read official documents before integrating Fluwx. Then you'll understand how to generate Android signature, what's universal link for iOS, how to add URL schema for iOS and so on.

Install

Add the fluwx package (with payment feature by default) in your pubspec.yaml file:

fluwx with pay:

dependencies:
  fluwx: ^${latestVersion}

[!WARNING] Never forget to replace ^${latestVersion} with an actual version!
(See the above version, or go to versions on pub.dev)

[!WARNING] For no_pay version, you will need switch to fluwx_no_pay package, which is a separate package without payment features.

Configurations

Fluwx enables multiple configurations in the section fluwx of pubspec.yaml from v4, you can reference pubspec.yaml for more details.

• app_id. This is not used to init WeChat SDK so you still need to call fluwx.registerApi manually.

• debug_logging. Optional. Enable logs by setting it true. It's not working on iOS for now.

• flutter_activity. Optional. This is usually used by cold boot from WeChat on Android. Fluwx will try to launch launcher activity if not set.

• On OpenHarmony, to check if WeChat is installed, add the following to the module.json5 in your project

{
  "module": {
    "querySchemes": [
      "weixin"
    ],
  }
}

HarmonyOS Debugging Notice: Do not use the IDE's automatic signing. You must manually apply for a debug certificate for signing and debugging.

Register WxAPI

Register your app via fluwx if necessary.

Fluwx fluwx = Fluwx();
final success = fluwx.registerApi(appId: "wxd930ea5d5a228f5f",universalLink: "https://your.univerallink.com/link/");
print("register API success: $success");

iOS

The parameter universalLink only works with iOS. You can read this document to learn how to create universalLink and what additional configuration is needed on iOS. In what follows is a summary:

1. A valid iOS universal link for this app is needed.

2. Make sure the app has the entitlement Associated domains enabled

3. Add or modify LSApplicationQueriesSchemes in Info.plist in your iOS project. This is essential. The following strings should be added: weixin, wechat, weixinULAPI and weixinURLParamsAPI.

4. Add or modify CFBundleURLTypes in Info.plist in your iOS project. Add a URL type with name weixin and role editor. Put your WeChat App ID in URL Schemes. Example how this looks like in Info.plist after modifying via XCode:

<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLName</key>
			<string>weixin</string>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>wx123456789</string>
			</array>
		</dict>
	</array>

Android

Make sure the MD5 fingerprint of the signature of your app is registered at WeChat. You can extract this signature from your keystore using Java's keytool.

In debug mode your app is signed with a debug key from the development machine which will not be recognized by WeChat and you'll get errCode = -1. If you want to test in debug mode you will have to modify your debug key

You can read more about it on this page.

It's better to register your API as early as possible.
