  'Automotive', 'Sports', 'Education',
  'Fashion', 'Travel', 'Food', 'Tech',
  'Science',
];

// ChipsChoice<T>.single
ChipsChoice<int>.single(
  value: tag,
  options: ChipsChoiceOption.listFrom<int, String>(
    source: options,
    value: (i, v) => i,
    label: (i, v) => v,
  ),
  onChanged: (val) => setState(() => tag = val),
);

List<String> tags = [];
List<String> options = [
  'News', 'Entertainment', 'Politics',
  'Automotive', 'Sports', 'Education',
  'Fashion', 'Travel', 'Food', 'Tech',
  'Science',
];

// ChipsChoice<T>.multiple
ChipsChoice<String>.multiple(
  value: tags,
  options: ChipsChoiceOption.listFrom<String, String>(
    source: options,
    value: (i, v) => v,
    label: (i, v) => v,
  ),
  onChanged: (val) => setState(() => tags = val),
);

Build Options List

options property is List<ChipsChoiceOption<T>>, it can be input directly as in the example below, more info about ChipsChoiceOption can be found on the API Reference

ChipsChoice<T>.single/multiple(
  ...,
  ...,
  options: <ChipsChoiceOption<T>>[
    ChipsChoiceOption<T>(value: 1, label: 'Entertainment'),
    ChipsChoiceOption<T>(value: 2, label: 'Education'),
    ChipsChoiceOption<T>(value: 3, label: 'Fashion'),
  ],
);

options also can be created from any list using helper provided by this package, like the example below

List<Map<String, String>> days = [
  { 'value': 'mon', 'title': 'Monday' },
  { 'value': 'tue', 'title': 'Tuesday' },
  { 'value': 'wed', 'title': 'Wednesday' },
  { 'value': 'thu', 'title': 'Thursday' },
  { 'value': 'fri', 'title': 'Friday' },
  { 'value': 'sat', 'title': 'Saturday' },
  { 'value': 'sun', 'title': 'Sunday' },
];

ChipsChoice<T>.single/multiple(
  ...,
  ...,
  options: ChipsChoiceOption.listFrom<T, Map<String, String>>(
    source: days,
    value: (index, item) => item['value'],
    label: (index, item) => item['title'],
  ),
);

Scrollable or Wrapped List

ChipsChoice<T>.single/multiple(
  ...,
  ...,
  isWrapped: false/true,
);
