createFlowDefinition method

Future<CreateFlowDefinitionResponse> createFlowDefinition({ required String flowDefinitionName, required FlowDefinitionOutputConfig outputConfig, required String roleArn, HumanLoopActivationConfig? humanLoopActivationConfig, HumanLoopConfig? humanLoopConfig, HumanLoopRequestSource? humanLoopRequestSource, List<Tag>? tags, })

Creates a flow definition.

May throw ResourceInUse. May throw ResourceLimitExceeded.

Parameter flowDefinitionName : The name of your flow definition.

Parameter outputConfig : An object containing information about where the human review results will be uploaded.

Parameter roleArn : The Amazon Resource Name (ARN) of the role needed to call other services on your behalf. For example, arn:aws:iam::1234567890:role/service-role/AmazonSageMaker-ExecutionRole-20180111T151298.

Parameter humanLoopActivationConfig : An object containing information about the events that trigger a human workflow.

Parameter humanLoopConfig : An object containing information about the tasks the human reviewers will perform.

Parameter humanLoopRequestSource : Container for configuring the source of human task requests. Use to specify if Amazon Rekognition or Amazon Textract is used as an integration source.

Parameter tags : An array of key-value pairs that contain metadata to help you categorize and organize a flow definition. Each tag consists of a key and a value, both of which you define.
