SnippetTemplate class

A declarative description of the card Siri shows alongside an intent's result.

App Intents renders these cards with SwiftUI, which a Flutter app has no way to supply — a Flutter widget tree cannot be handed to Siri. So instead of taking a view, this takes a small fixed layout (image, title, subtitle, labelled rows) that the generator turns into a concrete SwiftUI view. It is deliberately not a general-purpose UI language: anything beyond this shape belongs in the app itself, reached with openAppWhenRun.

Text fields accept two kinds of placeholder:

• {paramName} — an intent parameter, the same syntax as resultDialogTemplate. Works in every execution mode.
• {result.key} — a key of the map the Dart handler returns. Only available when the intent runs through FlutterBridge, because the URL scheme and cache modes hand off to the app and return before the handler has produced anything. Using one elsewhere is a code generation error.

Example:

@IntentSpec(
  identifier: 'com.example.app.createTask',
  title: 'Create Task',
  resultDialogTemplate: 'Created {title}',
  snippet: SnippetTemplate(
    title: '{title}',
    subtitle: 'Added to {result.listName}',
    systemImageName: 'checkmark.circle.fill',
    rows: [SnippetRow(label: 'Due', value: '{result.dueDate}')],
  ),
)
