deleteFunction method

Future<void> deleteFunction({ required String functionName, String? qualifier, })

Deletes a Lambda function. To delete a specific function version, use the Qualifier parameter. Otherwise, all versions and aliases are deleted.

To delete Lambda event source mappings that invoke a function, use DeleteEventSourceMapping. For AWS services and resources that invoke your function directly, delete the trigger in the service where you originally configured it.

May throw ServiceException. May throw ResourceNotFoundException. May throw TooManyRequestsException. May throw InvalidParameterValueException. May throw ResourceConflictException.

Parameter functionName : The name of the Lambda function or version.

Name formats

• Function name - my-function (name-only), my-function:1 (with version).
• Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.
• Partial ARN - 123456789012:function:my-function.

You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

Parameter qualifier : Specify a version to delete. You can't delete a version that's referenced by an alias.

Implementation

Future<void> deleteFunction({
  required String functionName,
  String? qualifier,
}) async {
  ArgumentError.checkNotNull(functionName, 'functionName');
  _s.validateStringLength(
    'functionName',
    functionName,
    1,
    140,
    isRequired: true,
  );
  _s.validateStringLength(
    'qualifier',
    qualifier,
    1,
    128,
  );
  final $query = <String, List<String>>{
    if (qualifier != null) 'Qualifier': [qualifier],
  };
  await _protocol.send(
    payload: null,
    method: 'DELETE',
    requestUri: '/2015-03-31/functions/${Uri.encodeComponent(functionName)}',
    queryParams: $query,
    exceptionFnMap: _exceptionFns,
  );
}
