DiagnosticsNode class abstract
Defines diagnostics data for a value.
For debug and profile modes, DiagnosticsNode provides a high quality multiline 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.
In release mode, far less information is retained and some information may not print at all.

Constructors
- DiagnosticsNode({required String? name, DiagnosticsTreeStyle? style, bool showName = true, bool showSeparator = true, String? linePrefix})
- Initializes the object.
- DiagnosticsNode.message(String message, {DiagnosticsTreeStyle style = DiagnosticsTreeStyle.singleLine, DiagnosticLevel level = DiagnosticLevel.info, bool allowWrap = true})
-
Diagnostics containing just a string
message
and not a concrete name or value.factory

Methods
-
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 nonexistent 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.
-
toJsonMap(
DiagnosticsSerializationDelegate delegate) → Map< String, Object?> - Serialize the node to a JSON map according to the configuration provided in the DiagnosticsSerializationDelegate.
-
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.
override
-
toStringDeep(
{String prefixLineOne = '', String? prefixOtherLines, TextTreeConfiguration? parentConfiguration, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → 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).
Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
Static Methods
-
toJsonList(
List< DiagnosticsNode> ? nodes, DiagnosticsNode? parent, DiagnosticsSerializationDelegate delegate) → List<Map< String, Object?> > - Serializes a List of DiagnosticsNodes to a JSON list according to the configuration provided by the DiagnosticsSerializationDelegate.
