jsonDecodeList function

List jsonDecodeList(dynamic json)

Decodes a JSON string into a List<dynamic>, always returning a list.

Returns an empty list for invalid or empty input.

final result = jsonDecodeList('[1, 2, 3]');
print(result); // [1, 2, 3]

final emptyResult = jsonDecodeList('');
print(emptyResult); // []

@ai Use when you need a list result regardless of input validity.

Implementation

List<dynamic> jsonDecodeList(final dynamic json) {
  if (json case final List list) return list;
  final jsonString = jsonDecodeString(json);
  if (jsonString.isEmpty) return [];
  return switch (jsonDecode(jsonString)) {
    final List list => list,
    _ => [],
  };
}
