toMap<K, V> function

Map<K, V> toMap<K, V>(dynamic object, { Object? mapKey, int? listIndex, })

Converts an object to a Map with keys of type K and values of type V. mirroring the same static method in the ConvertObject, providing alternative easy less code usage options.

• If the object is already a Map with the correct key and value types, it is returned as-is.
• If the object is an empty Map, an empty Map is returned.
• If the object is null, throws a ParsingException with a nullObject error.
• If the object cannot be converted to a Map with the specified types, throws a ParsingException.

object The object to be converted to a Map with keys of type K and values of type V. mapKey (Optional) Specifies the key to extract values from a Map object. listIndex (Optional) Specifies the index to extract elements from a List object.

Returns a Map<K, V> if conversion is successful. Throws a ParsingException if the conversion fails.

Example usage:

final object1 = {'key1': 'value1', 'key2': 'value2'};
final map1 = toMap<String, String>(object1); // {'key1': 'value1', 'key2': 'value2'}

final object2 = {'key1': 1, 'key2': 2};
final map2 = toMap<String, int>(object2); // {'key1': 1, 'key2': 2'}

final object3 = 'Hello';
final map3 = toMap<String, int>(object3); // ParsingException (logs an error)

final object4 = null;
final map4 = toMap<String, int>(object4); // ParsingException (null object)

Implementation

Map<K, V> toMap<K, V>(
  dynamic object, {
  Object? mapKey,
  int? listIndex,
}) =>
    ConvertObject.toMap(object, mapKey: mapKey, listIndex: listIndex);
