genui Changelog #

0.7.0 #

  • Fix: Improved error handling for catalog example loading to include context about the invalid item (#653).
  • BREAKING: Renamed ChatMessageWidget to ChatMessageView and InternalMessageWidget to InternalMessageView (#661).
  • Fix: Pass the correct catalogId in DebugCatalogView widget (#676).
  • Added some dart documentation and an example directory to improve package:genui pub score.
  • Fix: Make ContentGeneratorError be an Exception (#660).
  • Feature: Define genui parts as extensions of genai_primitives (#675).
  • Internal: Enable stricter dynamic-related analysis (#652).

0.6.1 #

  • Fix: Corrected DateTimeInput catalog item JSON key mapping (#622).
  • Fix: Added missing weight property to Component constructor (#603).
  • Fix: Defaulted TextField width to 1 when nested in a Row (#603).

0.6.0 #

  • BREAKING: Renamed GenUiManager to A2uiMessageProcessor to better reflect its role.
  • BREAKING: A2uiMessageProcessor now accepts an Iterable<Catalog> via catalogs instead of a single catalog.
  • BREAKING: Removed GenUiConfiguration and ActionsConfig.
  • BREAKING: Removed GenUiHost.catalog in favor of GenUiHost.catalogs.
  • Improved surface rendering logic to cache components before rendering.
  • Updated README sample code to reflect current FirebaseAiContentGenerator API (added catalog parameter and replaced tools with additionalTools).
  • Feature: GenUiManager now supports multiple catalogs by accepting an Iterable<Catalog> in its constructor.
  • Feature: A2uiMessageProcessor now supports multiple catalogs by accepting an Iterable<Catalog> in its constructor.
  • Feature: catalogId property added to UiDefinition to specify which catalog a UI surface should use.
  • Refactor: Moved standardCatalogId constant from core_catalog.dart to primitives/constants.dart for better organization and accessibility.
  • Fix: MultipleChoice widget now correctly handles maxAllowedSelections when provided as a double in JSON, preventing type cast errors.
  • Fix: The Text catalog item now respects the ambient DefaultTextStyle, resolving contrast issues where, for example, text inside a dark purple primary Button would be black instead of white.

0.5.1 #

  • Homepage URL was updated.
  • Deprecated flutter_markdown package was replaced with flutter_markdown_plus.

0.5.0 #

  • Initial published release.

0.4.0 #

  • BREAKING: Replaced AiClient interface with ContentGenerator. ContentGenerator uses a stream-based API (a2uiMessageStream, textResponseStream, errorStream) for asynchronous communication of AI-generated UI commands, text, and errors.
  • BREAKING: GenUiConversation now requires a ContentGenerator instance instead of an AiClient.
  • Feature: Introduced A2uiMessage sealed class (BeginRendering, SurfaceUpdate, DataModelUpdate, SurfaceDeletion) to represent AI-to-UI commands, emitted from ContentGenerator.a2uiMessageStream.
  • Feature: Added FakeContentGenerator for testing purposes, replacing FakeAiClient.
  • Feature: Added configureGenUiLogging function and genUiLogger instance for configurable package logging.
  • Feature: Added JsonMap type alias in primitives/simple_items.dart.
  • Feature: Added DirectCallHost and related utilities in facade/direct_call_integration for more direct AI model interactions.
  • Refactor: GenUiConversation now internally subscribes to ContentGenerator streams and uses callbacks (onSurfaceAdded, onSurfaceUpdated, onSurfaceDeleted, onTextResponse, onError) to notify the application of events.
  • Fix: Improved error handling and reporting through the ContentGenerator.errorStream and ContentGeneratorError class.

0.2.0 #

  • BREAKING: Replaced ElevatedButton with a more generic Button component.
  • BREAKING: Removed CheckboxGroup and RadioGroup from the core catalog. The MultipleChoice or CheckBox widgets can be used as replacements.
  • Feature: Added an obscured property to TextInputChip to allow for password style inputs.
  • Feature: Added many new components to the core catalog: AudioPlayer (placeholder), Button, Card, CheckBox, DateTimeInput, Divider, Heading, List, Modal, MultipleChoice, Row, Slider, Tabs, and Video (placeholder).
  • Fix: Corrected the action key from actionName to name in Trailhead and TravelCarousel.
  • Fix: Corrected the image property from location to url in TravelCarousel.
