DiagnosticsNode that exists mainly to provide a container for other diagnostics that typically lacks a meaningful value of its own.

This class is typically used for displaying complex nested error messages.

Methods

getChildren() List<DiagnosticsNode>
Children of this DiagnosticsNode.
override
getProperties() List<DiagnosticsNode>
Properties of this DiagnosticsNode.
override
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.
inherited
toDescription({TextTreeConfiguration? parentConfiguration}) String
Returns a description with a short summary of the node itself not including children or properties.
override

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.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, TextTreeConfiguration? parentConfiguration, DiagnosticLevel minLevel = DiagnosticLevel.debug}) String
