clear method Null safety

Future<void> clear(
  1. String tasklist,
  2. {String? $fields}
)

Clears all completed tasks from the specified task list.

The affected tasks will be marked as 'hidden' and no longer be returned by default when retrieving all tasks for a task list.

Request parameters:

tasklist - Task list identifier.

$fields - Selector specifying which fields to include in a partial response.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<void> clear(
  core.String tasklist, {
  core.String? $fields,
}) async {
  final _queryParams = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final _url =
      'tasks/v1/lists/' + commons.escapeVariable('$tasklist') + '/clear';

  await _requester.request(
    _url,
    'POST',
    queryParams: _queryParams,
    downloadOptions: null,
  );
}
