How to setup multiple flavors of app in Flutter?

[MarufHassanPietech]

Describe the bug We have a app which has three flavors - dev, stg, prod. We have created 3 apps in Branch.io dashboard for 3 flavors. My problem is with the info.plist file. How do I differentiate the different flavors for it?

Code

        <key>branch_key</key>
        <dict>
            <key>live</key>
            <string>key_live_cDfD4sdaasdcaim7Z</string>
            <key>test</key>
            <string>key_test_oEiBY3bdsdsdsnxmj</string>
        </dict>
        <key>branch_universal_link_domains</key>
        <array>
            <string>dsa.test-app.link</string>
            <string>bsd2-alternate.test-app.link</string>
            <string>dsas.app.link</string>
            <string>dadw-alternate.app.link</string>
        </array>

This code is for dev flavor according to Branch.io data[Not original keys & link]. How does my app differentiate if it should use this or any other data for a particular flavor. What should I write for other flavors?

@MarufHassanPietech

This package calls Branch Native SDK functions on each platform.

The doubt reported is not in the Flutter plugin, but in the Native SDK.

Please open an issue in the platform repository:

iOS: https://github.com/BranchMetrics/ios-branch-deep-linking-attribution Android: https://github.com/BranchMetrics/android-branch-deep-linking-attribution Or open a support ticket for Branch at the link

@MarufHassanPietech

In addition.

You don't need to create 3 applications.

Each application has 2 environments: Test and Production with different url and keys.

In the Branch configuration dashboard, there is a switch where you can see the settings for each environment.

You can configure the use of the test key, according to the REAME.MD instructions.

To save work for your environments, configure dev and stg to use the same key, which would be the test key.

[MarufHassanPietech]

@RodrigoSMarques I tried using only one app in Branch.io as you suggested. I have three flavors dev - Flavor.superbrains_dev, stg - Flavor.superbrains_stg, prod - Flavor.superbrains

This is my configuration in Android Manifest. [Not original keys & link]

      <!-- END: SUPERBRAINS BRANCH -->
      <!-- END: Code for Branch.io deeplink-->

In the main.dart file I have added this while initializing the app.

  await FlutterBranchSdk.init(
    useTestKey:
        flavor == Flavor.superbrains || flavor == Flavor.superbrains_stg,
    enableLogging: false,
    disableTracking: false,
  );
  FlutterBranchSdk.validateSDKIntegration();

While running the app in dev flavor I am getting this error.

Exception has occurred.

The Tag

<intent-filter android:autoVerify="true"> 

must be between <activity>and </activity>.

<meta-data
            android:name="io.branch.sdk.BranchKey" 

and

<meta-data
            android:name="io.branch.sdk.BranchKey.test" 

must be outside <activity> and inside <application> </application>

Sample here

You can verify?

Thank you. I took the reference you provided above and it worked.

@RodrigoSMarques , we have app with 3 different bundle identifiers for 3 flavors. So using single app in branch.io is not working for us

As I had previously reported.

This is a configuration question for the Branch SDK and not the plugin.

This plugin calls the SDK functions.

I suggest you open an issue directly with Branch.

iOS: https://github.com/BranchMetrics/ios-branch-deep-linking-attribution Android: https://github.com/BranchMetrics/android-branch-deep-linking-attribution Or open a support ticket for Branch at the link

You can also research how to have different INFO.PLIST on iOS, according to flavor, as each flavor needs to have different branch keys and different app links.
