credential_manager_platform_interface 4.0.0

A common platform interface for the credential_manager plugin. This package allows platform-specific implementations of credential_manager to share the same interface.

4.0.0

• Added AllowCredential ({id, type, transports}) and CredentialLoginOptions.allowCredentials, letting a relying party restrict which passkey the OS offers for a WebAuthn assertion. Previously the field was dropped before reaching the platform, so an account bound to a single passkey still showed a picker listing every credential registered for the rpId.
• CredentialLoginOptions.fromJson now filters out allowCredentials entries whose id is missing or not a String instead of throwing and failing the entire parse.
• Added a backward-compatible prepareCredentials platform hook that defaults to false on unsupported platforms, enabling Android 14+ credential prefetching.
• No breaking changes to the public Dart API.

3.0.0

• Breaking: CredentialManagerPlatform.saveGoogleCredential gains an optional named {String? nonce} parameter. This was actually added in a prior commit without a version bump — the package published as 2.0.8 on pub.dev predates this change and does not have nonce, which broke flutter pub get/analysis for anyone resolving credential_manager_platform_interface from pub.dev (this repo's own melos workspace masked it locally via path-based resolution). Publishing this as a new major version is a correction, not new API surface.
• Any external CredentialManagerPlatform implementation overriding saveGoogleCredential(bool useButtonFlow) without the nonce parameter will fail to compile against this version — add {String? nonce} to your override (Dart requires overrides to declare every named parameter of the overridden method, even optional ones).
• No other functional changes; remaining diffs since 2.0.8 are formatting-only (120-column reformat).

2.0.8

• Added isGmsAvailable to platform interface
• Handle exception code 209 for Google Play Services not available

2.0.6

• Added exceptions and utilities to platform interface package
• Exported CredentialException and related exception classes
• Exported utility classes: CredentialType, PlatformExceptionHandler, and CredentialResponseParser
• Improved modular architecture by centralizing shared code in platform interface

2.0.5

• Initial release of platform interface package
• Provides abstract CredentialManagerPlatform class
• Supports modular plugin architecture
