getChildren() List<DiagnosticsNode>
Children of this DiagnosticsNode.
getProperties() List<DiagnosticsNode>
Properties of this DiagnosticsNode.
isFiltered(DiagnosticLevel minLevel) bool
Whether the diagnostic should be filtered due to its level being lower than minLevel.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
toDescription({TextTreeConfiguration? parentConfiguration}) String

toString({TextTreeConfiguration? parentConfiguration, DiagnosticLevel minLevel = DiagnosticLevel.info}) String
Returns a string representation of this diagnostic that is compatible with the style of the parent if the node is not the root.
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, TextTreeConfiguration? parentConfiguration, DiagnosticLevel minLevel = DiagnosticLevel.debug}) String
Returns a string representation of this node and its descendants.
toTimelineArguments() Map<String, String>?
Converts the properties (getProperties) of this node to a form useful for Timeline event arguments (as in Timeline.startSync).
