Getting started #
To get the API key you have to create a Gemini account on the ai.google.dev. Once you have to Gemini API key, you are ready to start building.
Create Gemini Instance #
final gemini = GoogleGemini(
apiKey: "--- Your Gemini Api Key --- ",
);

Generate content #
With Gemini you use both text and image data for prompting, depending on what model variation you use.
For example, you can generate text using text prompt with the gemini-pro model and use both text and image data to prompt the gemini-pro-vision model
Text only input #
This feature lets you perform natural language processing (NLP) tasks such as text completion and summarization.
gemini.generateFromText("Tell me a story")
.then((value) => print(value.text))
.catchError((e) => print(e));

Text and image input #
You can send a text prompt with an image to the gemini-pro-vision model to perform a vision related task. For example, captioning an image or identifying what's in an image.
File image = File("assets/images.png")

gemini.generateFromTextAndImages(
query: "What is this picture?",
image: image
)
.then((value) => print(value.text))
.catchError((e) => print(e));

Configuration #
Every prompt you send to the model includes parameter values that control how the model generates a response. The model can generate different results for different parameter values.
Model parameters #
The most common model parameters are:


Max output tokens: Specifies the maximum number of tokens that can be generated in the response. A token is approximately four characters. 100 tokens correspond to roughly 60-80 words.


Temperature: The temperature controls the degree of randomness in token selection. Lower temperatures are good for prompts that require a more deterministic or less open-ended response, while higher temperatures can lead to more diverse or creative results.


topK: The topK parameter changes how the model selects tokens for output.


topP: The topP parameter changes how the model selects tokens for output.


stop_sequences: Set a stop sequence to tell the model to stop generating content. A stop sequence can be any sequence of characters. Try to avoid using a sequence of characters that may appear in the generated content.


Example
// Generation Configuration
final config = GenerationConfig(
temperature: 0.5,
maxOutputTokens: 100,
topP: 1.0,
topK: 40,
stopSequences: []
);

// Gemini Instance
final gemini = GoogleGemini(
apiKey: "--- Your Gemini Api Key ---",
config: config // pass the config here
);

Safety settings #
Safety settings are part of the request you send to the text service. It can be adjusted for each request you make to the API.
