What it does

Firebase AI is an agent skill from evanca/flutter-ai-rules. Use when setting up firebaseai, generating text/chat with Gemini, streaming AI output, building multimodal prompts, or handling AI errors.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with Firebase and Flutter. The repository describes itself as: Flutter AI Skills and Rules for Claude, Codex, Cursor, and Other AI-Powered IDEs. The licence is MIT.

When your agent uses it

Setting up firebaseai
Generating text/chat with Gemini
Streaming AI output
Building multimodal prompts

Example prompts

“/firebase-ai”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Setup and Configuration
Generating Content
Error Handling
Security and Privacy

What it can do on your machine

Read from SKILL.md and the folder at commit 7b9cce2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- flutter
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- firebase.google.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Firebase AI loads about 1.1k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 273 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Firebase AI Skill

This skill defines how to correctly use Firebase AI Logic in Flutter applications.

When to Use

Use this skill when:

Setting up and configuring Firebase AI in a Flutter project.
Generating text content or chat responses with Gemini models.
Implementing streaming AI responses for real-time UI updates.
Sending multimodal prompts (text + images) to Gemini.
Handling errors, offline scenarios, and rate limits for AI operations.
Applying security and privacy considerations for AI features.

1. Setup and Configuration

flutter pub add firebase_ai

dart

import 'package:firebase_ai/firebase_ai.dart';
import 'package:firebase_core/firebase_core.dart';
import 'firebase_options.dart';

// Initialize FirebaseApp
await Firebase.initializeApp(
  options: DefaultFirebaseOptions.currentPlatform,
);

// Initialize the Gemini Developer API backend service
final model =
    FirebaseAI.googleAI().generativeModel(model: 'gemini-2.5-flash');

Ensure the Firebase project is configured for AI services via the Firebase AI Logic page in the Firebase Console.
Initialize Firebase before using any Firebase AI features.
Use FirebaseAI.googleAI() for the Gemini Developer API backend (recommended starting point).
Implement App Check to prevent abuse of Firebase AI endpoints.

Platform support:

Platform	Support
iOS	Full
Android	Full
Web	Full
macOS / other Apple	Beta
Windows	Not supported

2. Generating Content

Single-turn text generation

dart

final response = await model.generateContent([
  Content.text('Summarize the benefits of Flutter for mobile development'),
]);
final text = response.text; // The generated summary string

Multi-turn chat

dart

final chat = model.startChat();
final response = await chat.sendMessage(
  Content.text('What is the difference between StatelessWidget and StatefulWidget?'),
);
print(response.text);

// Follow-up in the same conversation
final followUp = await chat.sendMessage(
  Content.text('When should I use StatefulWidget?'),
);
print(followUp.text);

Streaming responses

Use streaming to display partial results as they arrive:

dart

final stream = model.generateContentStream([
  Content.text('Write a step-by-step guide to implementing dark mode in Flutter'),
]);

await for (final chunk in stream) {
  // Append chunk.text to the UI progressively
  setState(() => _output += chunk.text ?? '');
}

Multimodal prompts (text + image)

dart

final imageBytes = await File('photo.jpg').readAsBytes();
final response = await model.generateContent([
  Content.multi([
    TextPart('Describe what you see in this image'),
    InlineDataPart('image/jpeg', imageBytes),
  ]),
]);

3. Error Handling

Wrap AI calls in structured error handling:

dart

try {
  final response = await model.generateContent([Content.text(prompt)]);
  return response.text;
} on FirebaseAIException catch (e) {
  if (e.message?.contains('quota') ?? false) {
    // Handle rate limiting — show retry message or queue the request
    return 'Service is busy. Please try again shortly.';
  }
  return 'AI service error: ${e.message}';
} catch (e) {
  return 'Unexpected error: $e';
}

Provide meaningful error messages to users when AI operations fail.
Handle offline scenarios with appropriate fallback behavior (e.g., cached responses).
Implement exponential backoff for rate-limited or transient errors.

4. Security and Privacy

Follow Firebase Security Rules best practices when using AI services alongside other Firebase products.
Ensure proper authentication and authorization for AI feature access.
Sanitize user input before sending it to the model to prevent prompt injection.
Be mindful of data privacy requirements when processing user content with AI services.
Implement appropriate content filtering and moderation using safety settings:

dart

final model = FirebaseAI.googleAI().generativeModel(
  model: 'gemini-2.5-flash',
  safetySettings: [
    SafetySetting(HarmCategory.harassment, HarmBlockThreshold.medium),
    SafetySetting(HarmCategory.dangerousContent, HarmBlockThreshold.high),
  ],
);
