Credential Manager

Credential Manager is a Jetpack API that supports multiple sign-in methods, such as username and password, passkeys, and federated sign-in solutions (like Sign-in with Google) in a single API, simplifying integration for developers.

For users, Credential Manager unifies the sign-in interface across authentication methods, making it clearer and easier to sign into apps, regardless of the chosen method.

Note: This package is currently only supported for Android.

Getting Started

Add the dependency to your pubspec.yaml file:

credential_manager: <latest_version>

Or run:

flutter pub add credential_manager

Setup Android

1. Add proguard rules: Create or update android/app/proguard-rules.pro:

   -if class androidx.credentials.CredentialManager
   -keep class androidx.credentials.playservices.** {
     *;
   }
   

2. Update android/app/build.gradle:

   android {
     buildTypes {
       release {
         minifyEnabled true
         proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
       }
     }
   }
   

Usage in Flutter

1. Import the package:

   import 'package:credential_manager/credential_manager.dart';
   

2. Create a CredentialManager instance:

3. Check if the platform is supported:

   if (credentialManager.isSupportedPlatform) {
     // Supported
   }
   

4. Initialize the Credential Manager:

   await credentialManager.init(
     preferImmediatelyAvailableCredentials: true,
     googleClientId: googleClientId // Optional for Google Sign-In
   );
   

5. Save credentials:

   await credentialManager.savePasswordCredentials(
     PasswordCredential(username: username, password: password)
   );
   

6. Save Google credentials:

   final GoogleIdTokenCredential? gCredential = await credentialManager.saveGoogleCredential();
   

   For Google button flow:

   await credentialManager.saveGoogleCredential(useButtonFlow: true);
