Constructors

AttributedStringProperty(String name, AttributedString? value, {bool showName = true, bool showWhenEmpty = false, Object? defaultValue = kNoDefaultValue, DiagnosticLevel level = DiagnosticLevel.info, String? description})

Properties

allowNameWrap → bool
Whether to wrap the name onto multiple lines or not.
finalinherited
allowTruncate → bool
Whether to allow truncation when displaying the node and its children.
read-onlyinherited
allowWrap → bool

read-onlyoverride
level → DiagnosticLevel

read-onlyinherited
linePrefix → String?

finalinherited
missingIfNull → bool
Whether a value of null causes the property to have level DiagnosticLevel.warning warning that the property is missing a value.
finalinherited
name → String?
Label describing the DiagnosticsNode, typically shown before a separator (see showSeparator).
finalinherited
propertyType → Type
The type of the property value.
read-onlyinherited
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited
showName → bool

final
style → DiagnosticsTreeStyle?
Hint for how the node should be displayed.
finalinherited
textTreeConfiguration → TextTreeConfiguration?
Returns a configuration specifying how this object should be rendered as text art.

Methods

getChildren() → List<DiagnosticsNode>
Children of this DiagnosticsNode.
inherited
getProperties() → List<DiagnosticsNode>
Properties of this DiagnosticsNode.
inherited
isFiltered(DiagnosticLevel minLevel) → bool
Whether the diagnostic should be filtered due to its level being lower than minLevel.
inherited
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.
inherited
toJsonMap(DiagnosticsSerializationDelegate delegate) → Map<String, Object?>
Serialize the node to a JSON map according to the configuration provided in the DiagnosticsSerializationDelegate.
inherited
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
Returns a string representation of this node and its descendants.
inherited
toTimelineArguments() → Map<String, String>?
Converts the properties (getProperties) of this node to a form useful for Timeline event arguments (as in Timeline.startSync).
inherited
valueToString({TextTreeConfiguration? parentConfiguration}) → String
Returns a string representation of the property value.
