cobalt_talker example #

Each kind of Cobalt event becomes its own TalkerLog type, with its own title and colour — which is the reason to reach for talker rather than a plain sink.

import 'package:cobalt/cobalt.dart';
import 'package:cobalt_talker/cobalt_talker.dart';
import 'package:talker/talker.dart';

final talker = Talker();

final scope = await CobaltApplication.start(
  root: const AppScope(),
  observers: [CobaltTalkerObserver(talker)],
);

The log then carries cobalt-scope, cobalt-startup, cobalt-instance and cobalt-failure entries as separate, colour-coded types. Those four titles are also the keys talker_flutter colours rows by, which is what lets cobalt_talker_flutter dress its screen in the same palette as the inspector.

Per-instance records are off by default — on a real graph they drown the signal the log was opened for. Turn them on deliberately:

CobaltTalkerObserver(talker, verbose: true)

With talker_flutter, TalkerScreen shows the whole thing live; that is what examples/graph_events does.
