google_generative_ai 0.4.2

The Google AI Dart SDK enables developers to use Google's state-of-the-art generative AI models (like Gemini).

0.4.2

• Add support for GenerationConfig.responseSchema for constraining JSON mime type output formats.
• Require Dart 3.1.

0.4.1

• Concatenate multiple TextPart into the text String in case the model replies with more than one part.
• Fix handling of format argument to Schema.number and Schema.integer.
• Export UsageMetadata.
• Include the full GenerateContentRequest (previously omitted safetySettings, generationConfig, tools, toolConfig, and systemInstruction) in countTokens requests. This aligns the token count with the token count the backend will see in practice for a generateContent request.
• Add a text getter on Candidate to make it easer to retrieve the text from candidates other than the first in a response.

0.4.0

• Add support for parsing Vertex AI specific fields in CountTokensResponse.
• Add named constructors on Schema for each value type.
• Add GenerationConfig.responseMimeType which supports setting 'application/json' to force the model to reply with JSON parseable output.
• Add outputDimensionality argument support for embedContent and batchEmbedContent.
• Add Content.functionResponses utility to reply to multiple function calls in parallel.
• Breaking The Part class is no longer sealed. Exhaustive switches over a Part instance will need to add a wildcard case.

0.3.3

• Add support for parsing the usageMetadata field in GenerateContentResponse messages.

0.3.2

• Use API version v1beta by default.
• Add note to README warning about leaking API keys.

0.3.1

• Add support on content generating methods for overriding "tools" passed when the generative model was instantiated.
• Add support for forcing the model to use or not use function calls to generate content.

0.3.0

• Allow specifying an API version in a requestOptions argument when constructing a model.
• Add support for referring to uploaded files in request contents.
• Add support for passing tools with functions the model may call while generating responses.
• Add support for passing a system instruction when creating the model.
• Breaking Added new subclasses FilePart, FunctionCall, and FunctionResponse of the sealed class Part.

0.2.3

• Update the package version that is sent with the HTTP client name.
• Throw more actionable error objects than FormatException for errors. Errors were previously only correctly parsed in generateContent calls.
• Add support for tuned models.
• Add support for batchEmbedContents calls.

0.2.2

• Remove usage of new SDK features - support older SDKs 3.0 and above.

0.2.1

• Fix an issue parsing generateContent() responses that do not include content (this can occur for some finishReasons).
• Fix an issue parsing generateContent() responses that include citation sources with unpopulated fields
• Add link to ai.google.dev docs.

0.2.0

• Breaking HarmCategory.unknown renamed to unspecified. Removed unused unknown values in the HarmProbability and FinishReason enums.
• Add additional API documentation.
• Update the getting started instructions in the readme.

0.1.0

• Initial release.
