genui Changelog #

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.

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

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.

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.
