# resolve method

Class? resolve([

1. Class? fallback

])

Resolves this ResolvableType to a Class, returning null if the type cannot be resolved.

This is the primary method for converting a ResolvableType to a concrete Class instance that can be used for reflection operations, instantiation, and other runtime type operations.

Parameters:

- `fallback`: Optional Class to return if resolution fails

Returns:

- Class instance representing this ResolvableType
- The fallback Class if provided and resolution fails
- null if resolution fails and no fallback is provided

Example:

    final stringType = ResolvableType.forClass(String);
    final listType = ResolvableType.forClass(List<int>);
    final unknownType = ResolvableType.NONE;

    final stringClass = stringType.resolve();
    print(stringClass?.getType()); // String

    final listClass = listType.resolve();
    print(listClass?.getType()); // List<int>

    final unknownClass = unknownType.resolve();
    print(unknownClass); // null

    // With fallback
    final objectFallback = Class.forType(Object);
    final unknownWithFallback = unknownType.resolve(objectFallback);
    print(unknownWithFallback?.getType()); // Object

    // Useful for safe operations
    void processType(ResolvableType type) {
      final clazz = type.resolve();
      if (clazz != null) {
        print("Processing ${clazz.getType()}");
        // Perform operations with the resolved class
      } else {
        print("Cannot resolve type");
      }
    }

## Implementation

    Class? resolve([Class? fallback]) {
      if (_resolved != null) return _resolved;

      final resolved = _resolveClass();
      _resolved = resolved;
      return resolved ?? fallback;
    }
