gemini_live 0.2.1

gemini_live: ^0.2.1 copied to clipboard

Added #

• Example app now supports in-app Gemini API key configuration via Settings UI.
  • Users can save/update/clear API keys directly from the app screen.
  • API key is persisted locally with shared_preferences.
• Added examples/ephemeral_token.dart:
  • demonstrates Live API connection using ephemeral tokens (auth_tokens/...)
  • uses GoogleGenAI(apiVersion: 'v1alpha')

Changed #

• Expanded Function Calling demo in the example app:
  • added richer tool declarations:
    • get_exchange_rate
    • convert_currency
    • search_places
    • create_reminder (non-blocking)
  • improved simulated tool responses with structured payloads
  • added quick prompt chips for multi-tool scenarios
• Updated example/docs descriptions to reflect richer function calling capabilities.

Added #

• Expanded Live tool schema support:
  • Tool.functionDeclarations
  • Tool.googleSearch
  • Tool.googleSearchRetrieval
• Added richer function response fields:
  • FunctionResponse.scheduling
  • FunctionResponse.willContinue
  • FunctionResponse.parts
• Added Live generation config parity fields:
  • GenerationConfig.mediaResolution
  • GenerationConfig.speechConfig (voice config)
  • GenerationConfig.thinkingConfig
  • GenerationConfig.enableAffectiveDialog
  • GenerationConfig.seed
• Added additional Live server metadata parsing:
  • LiveServerContent.interrupted
  • LiveServerContent.waitingForInput
  • LiveServerContent.turnCompleteReason
  • LiveServerSetupComplete.sessionId
  • detailed UsageMetadata modality/token breakdown fields

Changed #

• Updated WebSocket connection behavior for Gemini Live ephemeral tokens:
  • auto-switches to BidiGenerateContentConstrained
  • uses access_token query parameter when API key starts with auth_tokens/
• Added apiVersion option to GoogleGenAI(...) so Live API version can be configured from the top-level client.
• Updated Live User-Agent version to google-genai-sdk/1.42.0.
• Updated enums and compatibility mapping for current Live API:
  • ActivityHandling.NO_INTERRUPTION (with backward-compatible alias)
  • VAD/voice activity typed signals
  • traffic/modality token metadata enums

Fixed #

• Fixed tool serialization so configured tools are actually sent in setup.
• Fixed session resumption parsing type for resumable (bool).
• Fixed GoAway parsing to align with timeLeft and added helper conversion to seconds (timeRemaining).
• Improved LiveServerMessage.text getter to ignore thought-only parts.
