## Integration with flutter_eval
To expose this API to mini-apps loaded via flutter_eval:
### Current Status
1. Add to plugin registry:
**FlutterEval Plugin Initialization: ✅ Complete**
- `flutterEvalPlugin` is properly initialized in `lib/modular/miniapp_loader.dart`
- Initialized from `main()` during app startup
- Plugin is shared between `miniapp_loader.dart` and `lib/modular/registry.dart`
- Runtime adds plugin when loading miniapps: `runtime.addPlugin(flutterEvalPlugin)`
**PaymentBridgePlugin: ✅ Created but not yet registered**
- Located at `lib/modular/api/payment_bridge.dart`
- Provides simplified wrapper around PaymentApi
- Designed for easier integration with eval bridge
**Full Eval Bridge: ⚠️ Requires Additional Setup**
To expose PaymentApi to miniapps through eval, you need to:
1. **Create EvalPlugin Implementation**
```dart
// In a new file: lib/modular/api/payment_eval_plugin.dart
import 'package:dart_eval/dart_eval_bridge.dart';
import 'package:island/modular/api/payment.dart';
import 'package:island/modular/api/payment_bridge.dart';
class PaymentEvalPlugin implements EvalPlugin {
@override
String get identifier => 'package:island/modular/api/payment.dart';
@override
void configureForCompile(BridgeDeclarationRegistry registry) {
// Define bridge classes for PaymentRequest, PaymentResult, CreateOrderRequest
// Requires using @Bind() annotations or manual bridge definition
}
@override
void configureForRuntime(Runtime runtime) {
// Register functions that miniapps can call
// This requires bridge wrapper classes to be generated or created manually
}
}
```
2. **Generate or Create Bridge Code**
- Option A: Use `dart_eval_annotation` package with `@Bind()` annotations
- Add annotations to PaymentApi classes
- Run `dart run build_runner build` to generate bridge code
- Option B: Manually create bridge wrapper classes
- Define `$PaymentRequest`, `$PaymentResult`, etc.
- Implement `$Instance` interface for each
- Register bridge functions in `configureForRuntime`
3. **Register Plugin in Registry**
```dart
// In lib/modular/registry.dart
import 'package:island/modular/api/payment.dart';
import 'package:island/modular/api/payment_eval_plugin.dart';
Future<PluginLoadResult> loadMiniApp(...) async {
// ... existing code ...
final runtime = Runtime(ByteData.sublistView(bytecode));
runtime.addPlugin(flutterEvalPlugin);
// Register Payment API
final paymentAPI = PaymentAPI.instance;
// You'll need to create a bridge to expose this to eval
runtime.addPlugin(PaymentEvalPlugin()); // Add payment API plugin
// ... rest of loading code
}
```
2. Mini-app can access API:
4. **Mini-app Usage**
```dart
// mini_app/main.dart
final paymentAPI = PaymentAPI.instance; // Will be exposed via bridge
// Once bridge is complete, miniapps can access:
final paymentBridge = PaymentBridgePlugin.instance;
final result = await paymentBridge.processDirectPayment(
orderId: 'order_123',
amount: 1000,
currency: 'USD',
pinCode: '123456',
);
```
### Simplified Alternative
For quick testing without full bridge setup, miniapps can use the example pattern:
```dart
// Simulate API calls in miniapp for testing
Future<void> _testPayment() async {
setState(() => _isLoading = true);
try {
await Future.delayed(const Duration(seconds: 2));
setState(() => _status = 'Payment successful!');
} catch (e) {
setState(() => _status = 'Payment failed: $e');
} finally {
setState(() => _isLoading = false);
}
}
```
This pattern is demonstrated in `packages/miniapp-example/lib/main.dart`.
## Security Considerations
- **Never hardcode PIN codes**: Always get from user input
