stem_builder example #

This example demonstrates:

Annotated workflow/task definitions
Generated stemModule
Generated typed workflow refs (no manual workflow-name strings):
- StemWorkflowDefinitions.flow.start(runtime, params: (...))
- StemWorkflowDefinitions.userSignup.start(runtime, params: (...))
Generated typed task definitions that use the shared TaskCall / TaskDefinition.waitFor(...) APIs
Generated zero-arg task definitions with direct helpers from core:
- StemTaskDefinitions.builderExamplePing.enqueueAndWait(stem)
Generated workflow manifest via stemModule.workflowManifest
Running generated definitions through StemWorkflowApp
Runtime manifest + run/step metadata views via WorkflowRuntime

Run #

cd packages/stem_builder/example

dart pub get

dart run build_runner build

dart run bin/main.dart

dart run bin/runtime_metadata_views.dart

The checked-in lib/definitions.stem.g.dart is only a starter snapshot; rerun build_runner after changing annotations.

The generated bundle is the default integration surface:

StemWorkflowApp.inMemory(module: stemModule)
StemWorkflowApp.fromUrl(..., module: stemModule)
stemApp.createWorkflowApp() when the shared app already covers the workflow queue
StemClient.fromUrl(..., module: stemModule) + createWorkflowApp()
