DefaultApplicationStartup class

A no-op implementation of ApplicationStartup that always returns a singleton DefaultStartupStep for any startup operation.

This implementation is useful when:

• Startup tracking is disabled.
• Running in test environments.
• Using lightweight deployments where startup monitoring is unnecessary.

The returned DefaultStartupStep does nothing when you call methods like tag or end, making it safe to use in place of a fully functional startup tracker.

Example

void main() {
  final startup = DefaultApplicationStartup();

  // Start a step
  final step = startup.start('context.load');

  // These calls do nothing in the no-op implementation
  step.tag('key', 'value');
  step.end();
}
