Dartdoc template names are inconsistent #69252
Description
if you search for "@template" in the engine/src/flutter/lib/ui directory you'll find a variety of patterns:
window.dart
325: /// {@template flutter.lib.ui.window.accessorForwardWarning}
592: /// {@template flutter.lib.ui.window.functionForwardWarning}
text.dart
435:/// {@template flutter.dart:ui.textHeightBehavior}
1641: /// {@template flutter.dart:ui.boxHeightStyle.includeLineSpacing}
painting.dart
22:/// {@template flutter.dart:ui.imageFormats}
4852: /// {@template dart.ui.shadow.lerp}
compositing.dart
88:/// {@template dart.ui.sceneBuilder.oldLayerCompatibility}
258: /// {@template dart.ui.sceneBuilder.oldLayer}
264: /// {@template dart.ui.sceneBuilder.oldLayerVsRetained}
#platform_dispatcher.dart#
16:/// {@template dart.ui.TimingsCallback.list}
213: /// {@template flutter.foundation.PlatformDispatcher.onBeginFrame}
240: /// {@template flutter.foundation.PlatformDispatcher.onDrawFrame}
1137: /// {@template dart.ui.FrameTiming.fps_smoothness_milliseconds}
1141: /// {@template dart.ui.FrameTiming.fps_milliseconds}
platform_dispatcher.dart
16:/// {@template dart.ui.TimingsCallback.list}
213: /// {@template flutter.foundation.PlatformDispatcher.onBeginFrame}
240: /// {@template flutter.foundation.PlatformDispatcher.onDrawFrame}
1137: /// {@template dart.ui.FrameTiming.fps_smoothness_milliseconds}
1141: /// {@template dart.ui.FrameTiming.fps_milliseconds}
We should settle on one prefix for this library and use it consistently.
