WebConsolePrinter class

Chrome DevTools-native log printer for web platforms.

Uses %c CSS styling on console.groupCollapsed (via custom @JS bindings) to give group headers severity-appropriate colors derived from StyleResolver.defaultLevelColors. Body content uses:

  • console.log for message text (no auto-appended Chrome call stack)
  • console.dir for structured data (native expandable object tree)
  • %c-styled console.log for exceptions (red text)
  • StackTraceParser-formatted text for stack traces (aligned columns, internal frames filtered)

This printer is the default on web platforms (see printer_factory_web.dart). On native platforms, ComposablePrinter with environment-detected presets is used instead.

Constructors

WebConsolePrinter({int methodCount = 8, int? errorMethodCount, bool suppressTypeNames = false})

Properties

errorMethodCount → int?

runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
suppressTypeNames → bool
When true, suppresses LogEntry.loggerName from the label header. dart compile js minifies type names in release builds while leaving dart.vm.product as false — set this explicitly to true in production web bundles to avoid [c8.fn]-style noise.
