getStringList method

List<String>? getStringList(
  1. String key
)

Reads a set of string values from persistent storage, throwing an exception if it's not a string list.

Implementation

List<String>? getStringList(String key) {
  List<dynamic>? list = _preferenceCache[key] as List<dynamic>?;
  list = list?.cast<String>();
  // Make a copy of the list so that later mutations won't propagate
  return list?.toList() as List<String>?;
}
