DiagnosticsNode class

Defines diagnostics data for a value.

DiagnosticsNode provides a high quality multi-line string dump via toStringDeep. The core members are the name, toDescription, getProperties, value, and getChildren. All other members exist typically to provide hints for how toStringDeep and debugging tools should format output.

DiagnosticsNode.message(String message, { DiagnosticsTreeStyle style: DiagnosticsTreeStyle.singleLine, DiagnosticLevel level: DiagnosticLevel.info })
Diagnostics containing just a string message and not a concrete name or value. [...]


emptyBodyDescription String
Description to show if the node has no displayed properties or children.
level DiagnosticLevel
Priority level of the diagnostic used to control which diagnostics should be shown and filtered. [...]
name String
Label describing the DiagnosticsNode, typically shown before a separator (see showSeparator). [...]
showName bool
Whether the name of the property should be shown when showing the default view of the tree. [...]
showSeparator bool
Whether to show a separator between name and description. [...]
style DiagnosticsTreeStyle
Hint for how the node should be displayed.
textTreeConfiguration TextTreeConfiguration
Returns a configuration specifying how this object should be rendered as text art.
@protected, read-only
value Object
The actual object this is diagnostics data for.
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type

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. [...]
toDescription({TextTreeConfiguration parentConfiguration }) String
Returns a description with a short summary of the node itself not including children or properties. [...]
toJsonMap() Map<String, Object>
Serialize the node excluding its descendents to a JSON map. [...]
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. [...]
noSuchMethod(Invocation invocation) → dynamic
