Description

Hi there,

We are experiencing (and had experienced) a recurring issue across multiple projects in our company, all using the same plugin. The error occurs specifically on Android when trying to initialize the Gigya SDK:

I/flutter (15108): Failed to initialize the Gigya SDK.
I/flutter (15108): MissingPluginException(No implementation found for method initSdk on channel 
com.sap.gigya_flutter_plugin/methods)

Key Details

The issue occurs only on Android.
The issue occurs from version 1.0.0 to the latest 1.0.7.
It's happening across at least 11 projects.
It has been present on all versions of Flutter we've used for the past year and a half.
The issue appears in debug mode, so it's not related to shrinking, minification, or obfuscation.
Once the initial integration is done, everything works fine, even in release builds (with appropriate Proguard rules applied).

Solution

Remembering the pubspec.yaml of your example in version 1.0.0 gigya-flutter-plugin-1.0.0.zip, you were implementing the _flutter_facebookauth: ^4.1.2:

name: gigya_flutter_plugin_example
description: Demonstrates how to use the gigya_flutter_plugin plugin.
version: 1.0.0
homepage: https://www.sap.com
publish_to: none

environment:
  sdk: ">=2.18.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  flutter_facebook_auth: ^4.1.2
  gigya_flutter_plugin:
    # When depending on this package from a real application you should use:
    #   gigya_flutter_plugin: ^x.y.z
    # See https://dart.dev/tools/pub/dependencies#version-constraints
    # The example app is bundled with the plugin so we use a path dependency on
    # the parent directory to use the current plugin's version.
    path: ../

  google_sign_in: ^5.2.4

dev_dependencies:
  flutter_lints: ^2.0.0

  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true

  assets:
    - assets/

I found that adding the flutter_facebook_auth dependency to the pubspec.yaml resolves the issue. The dependency doesn't seem to be directly related to the Gigya SDK. Actually i cannot understand why this is solving the issue.

Request:

Could anyone provide insights on why adding the flutter_facebook_auth dependency resolves the issue? I would like to better understand the root cause of this. If is it a mandatory dependency to have in our pubspec.yaml why is it not mentioned in the readme guide?

Thank you for your time!

Reproduction
