将集转换为列表

Question

在Flutter中将Set<>转换为List<String>时需要帮助

Set<_Filter> _selectedFilters = Set<_Filter>();

final List<_Filter> _filters = [
  _Filter('Bee Cattle'),
  _Filter('Crops'),
  _Filter('Machinery'),
  _Filter('Fish'),
  _Filter('Sheep'),
  _Filter('Cattle Breeds'),
  _Filter('Wells'),
  _Filter('Farm'),
];

我需要将此Set转换为List<string>。

Answer 1

您可以简单地使用Iterable.toList method，也就是Set.toList。

final Set<String> set = {'cake', 'cookie'};

final List<String> list = set.toList();
