wrapNativeReturnValue method

Object? wrapNativeReturnValue(Object? nativeValue)

Wraps a native return value from a bridged call in a BridgedInstance if a bridge exists, otherwise returns the value as-is.

This is needed when bridged static getters or methods return instances of private subclasses (e.g., Curves.linear returns _Linear which extends Curve). The private class instance needs to be wrapped using the public superclass bridge.

Implementation

Object? wrapNativeReturnValue(Object? nativeValue) {
  if (nativeValue == null ||
      nativeValue is String ||
      nativeValue is num ||
      nativeValue is bool) {
    return nativeValue;
  }
  if (nativeValue is BridgedInstance) {
    return nativeValue;
  }
  if (nativeValue is List) {
    return nativeValue.map(wrapNativeReturnValue).toList();
  }
  if (nativeValue is Map) {
    return nativeValue.map(
      (key, value) =>
          MapEntry(wrapNativeReturnValue(key), wrapNativeReturnValue(value)),
    );
  }
  // Try to find a bridge for this native value
  final result = toBridgedInstance(nativeValue);
  if (result.$2) {
    return result.$1;
  }
  // No bridge found, return the value as-is
  return nativeValue;
}
