# resolveType method

ResolvableType resolveType()

Resolves this type by a single level, returning the resolved value or NONE.

This method attempts to resolve one level of type indirection, such as resolving type variables through their bounds or resolving types through type providers and variable resolvers.

Returns:

- ResolvableType representing the resolved type
- ResolvableType.NONE if resolution is not possible
- this if no resolution is needed

Example:

    // For a type variable T with bounds
    final typeVariable = ResolvableType.forTypeVariable(someTypeVariable);
    final resolved = typeVariable.resolveType();
    // resolved might be the bound type or a more concrete type

    // For array types with unresolved component types
    final arrayType = ResolvableType.forArrayComponent(someUnresolvedType);
    final resolvedArray = arrayType.resolveType();
    // resolvedArray has a resolved component type

    // Useful for incremental type resolution
    ResolvableType fullyResolve(ResolvableType type) {
      ResolvableType current = type;
      ResolvableType resolved = current.resolveType();
      while (resolved != current && resolved != ResolvableType.NONE) {
        current = resolved;
        resolved = current.resolveType();
      }
      return current;
    }

## Implementation

    ResolvableType resolveType() {
      if (this == NONE) return NONE;

      // Try to resolve the type through the type provider
      if (_typeProvider != null) {
        final providerType = _typeProvider.getType();
        if (providerType != null && providerType != _type) {
          return forType(providerType);
        }
      }

      // Try to resolve through variable resolver
      if (_variableResolver != null) {
        final resolved = _variableResolver.resolveVariable(_type);
        if (resolved != null && resolved != this) {
          return resolved;
        }
      }

      // Try to resolve generic bounds
      if (_isUnresolvableTypeVariable()) {
        // For type variables, try to get bounds
        final resolved = resolve();
        if (resolved != null) {
          return forType(resolved.getType());
        }
      }

      // For arrays, ensure component type is resolved
      if (isArray() && _componentType == null) {
        final componentType = _resolveComponentType();
        if (componentType != NONE) {
          return ResolvableType._(_type, _typeProvider, _variableResolver, componentType: componentType);
        }
      }

      return this;
    }
