AIBridge class

The main entry point for Flutter AI Bridge.

AIBridge ties together providers, routing, conversation management, cost control, and caching into a single, easy-to-use API.

final bridge = AIBridge(
  providers: [
    OpenAIProvider(config: AIConfig(apiKey: 'sk-...', model: 'gpt-4o')),
    GeminiProvider(config: AIConfig(apiKey: 'AI...', model: 'gemini-2.0-flash')),
  ],
  strategy: RoutingStrategy.costOptimized,
  budget: TokenBudget(maxTokensPerDay: 100000),
);

final response = await bridge.complete('Hello, AI!');
