listTaskDefinitionFamilies method

Future<ListTaskDefinitionFamiliesResponse> listTaskDefinitionFamilies({
  1. String? familyPrefix,
  2. int? maxResults,
  3. String? nextToken,
  4. TaskDefinitionFamilyStatus? status,
})

Returns a list of task definition families that are registered to your account (which may include task definition families that no longer have any ACTIVE task definition revisions).

You can filter out task definition families that do not contain any ACTIVE task definition revisions by setting the status parameter to ACTIVE. You can also filter the results with the familyPrefix parameter.

May throw ServerException. May throw ClientException. May throw InvalidParameterException.

Parameter familyPrefix : The familyPrefix is a string that is used to filter the results of ListTaskDefinitionFamilies. If you specify a familyPrefix, only task definition family names that begin with the familyPrefix string are returned.

Parameter maxResults : The maximum number of task definition family results returned by ListTaskDefinitionFamilies in paginated output. When this parameter is used, ListTaskDefinitions only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListTaskDefinitionFamilies request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitionFamilies returns up to 100 results and a nextToken value if applicable.

Parameter nextToken : The nextToken value returned from a ListTaskDefinitionFamilies request indicating that more results are available to fulfill the request and further calls will be needed. If maxResults was provided, it is possible the number of results to be fewer than maxResults.

Parameter status : The task definition family status with which to filter the ListTaskDefinitionFamilies results. By default, both ACTIVE and INACTIVE task definition families are listed. If this parameter is set to ACTIVE, only task definition families that have an ACTIVE task definition revision are returned. If this parameter is set to INACTIVE, only task definition families that do not have any ACTIVE task definition revisions are returned. If you paginate the resulting output, be sure to keep the status value constant in each subsequent request.

  String? nextToken,
  TaskDefinitionFamilyStatus? status,

  final jsonResponse = await _protocol.send(
    method: 'POST',
