exceptions

Exception types for the Modularity framework.

All exceptions extend ModularityException, which implements Exception for backward compatibility with existing catch clauses.

try {
  await controller.initialize(registry);
} on CircularDependencyException catch (e) {
  print('Cycle: ${e.dependencyChain}');
} on DependencyNotFoundException catch (e) {
  print('Missing: ${e.requestedType}, available: ${e.availableTypes}');
} on ModularityException catch (e) {
  print('Framework error: ${e.message}');
}
