Dart's logging package defines several logging levels. Below are the guidelines and examples for each level.

Guideline: Can use on any continuous user interaction, hovering, every paint cycle, etc.

Example:

logger.finest('User hovered over button with ID: $buttonId');

Guideline: ONLY USER EVENTS excluding ones that are continuously called (i.e., no hovering, but clicks are ok).

Example:

logger.finer('User clicked on button with ID: $buttonId');

Guideline: More high-level user events.

Example:

logger.fine('User completed the signup process.');

Guideline: Log configuration details.

Example:

logger.config('Application configuration loaded: $configSettings');

Guideline: General informational messages.

Example:

logger.info('User successfully logged in.');

Guideline: Potentially harmful situations.

Example:

logger.warning('API call failed, retrying...');

Guideline: Serious errors that require immediate attention.

Example:

logger.severe('Database connection failed: $error');

Guideline: Extremely severe issues that may cause the application to abort.

Example:

logger.shout('Out of memory error: system shutting down!');
