0.2.0 - 2026-08-09

Changed

• firebase_analytics floor raised to ^12.0.0 (latest major; verified against both 12.0.0 and the current 12.4.x).

• All attribute keys are now typed constants: enduser.id comes from the registry Enduser enum, analytics.user_property.value joined FirebaseAnalyticsSemantics, and the analytics.parameters. fan-out prefix is the exported analyticsParametersPrefix constant. No emitted keys changed.

• Semantic conventions updated to the current OTel registry: deprecated attribute keys are no longer emitted (db.system -> db.system.name, db.operation -> db.operation.name, rpc.system -> rpc.system.name, with rpc.service folded into a fully-qualified rpc.method).

• Dependency floors raised to dartastic_opentelemetry ^1.1.0-beta.12 and dartastic_opentelemetry_api ^1.0.0-rc.1. The previous floors declared compatibility with API versions that predate the semconv enums this package uses and could not actually resolve-and-compile.

• repository URL corrected to the canonical Dartastic org casing so pub.dev repository verification succeeds.

Added

• example/example.md — end-to-end walkthrough (init, traced calls, resulting trace shape).
• Extension methods on FirebaseAnalytics:
  • tracedLogEvent — emits a CLIENT span named analytics <event> with analytics.system, analytics.event.name, and a flat analytics.parameters.<key> for each entry in the supplied parameters map.
  • tracedLogScreenView — emits a span named analytics screen_view with analytics.screen.name / analytics.screen.class attributes.
  • tracedSetUserId — emits a span and attaches the supplied UID as enduser.id so downstream traces show the user identity that was just set.
  • tracedSetUserProperty — emits a span carrying analytics.user_property.name and .value.
• tracedAnalyticsCall<R>({eventName, invoke, parameters, extraAttrs}) — the generic helper underneath the extension methods. Useful when you can't or don't want to use a real FirebaseAnalytics (testing, custom backends).
• runWithoutFirebaseAnalyticsInstrumentation / runWithoutFirebaseAnalyticsInstrumentationAsync — zone-scoped suppression helpers.
• FirebaseAnalyticsSemantics — typed attribute-key enum for the analytics.* keys.
• Tests cover the full span shape (system + event + flat parameters with type coercion), extraAttrs without prefix, null-value skipping, exception path, suppression scope, and parent-span inheritance.
