Upgrade Guide

From 0.9.0 to 1.0.0

New Features Used

1. Budget Configuration

   // Before: No budget support
   
   // After: With budget limits
   provider.setBudgetConfig(
     const BudgetConfig(
       perSession: 1.0,
       onBudgetExceeded: 'warn',
     ),
   );
   

2. Cost Tracking

   // Before: No cost tracking
   
   // After: Automatic cost tracking
   await provider.generate(prompt);
   print('Cost: \$${provider.totalCost}');
   

3. Streaming

   // Before: Only regular generation
   
   // After: Stream tokens
   provider.generateStream(prompt).listen((token) {
     print(token);
   });
   

4. Retry Logic

   // Before: Manual retry handling
   
   // After: Automatic with executeWithRetry
   await provider.executeWithRetry(
     () => provider.generate(prompt),
     maxAttempts: 3,
   );
