DoubleProperty class - foundation library

Constructors

DoubleProperty(String name, double? value, {String? ifNull, String? unit, String? tooltip, Object? defaultValue = kNoDefaultValue, bool showName = true, DiagnosticsTreeStyle style = DiagnosticsTreeStyle.singleLine, DiagnosticLevel level = DiagnosticLevel.info}): If specified, unit describes the unit for the value (e.g. px).
DoubleProperty.lazy(String name, ComputePropertyValueCallback<double> computeValue, {String? ifNull, bool showName = true, String? unit, String? tooltip, Object? defaultValue = kNoDefaultValue, DiagnosticLevel level = DiagnosticLevel.info}): Property with a value that is computed only when needed.

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.
no setterinherited
allowWrap → bool: Whether to wrap text on onto multiple lines or not.
finalinherited
defaultValue → Object?: The default value of this property, when it has not been set to a specific value.
finalinherited
emptyBodyDescription → String?: Description to show if the node has no displayed properties or children.
no setterinherited
exception → Object?: Exception thrown if accessing the property value threw an exception.
no setterinherited
expandableValue → bool: Whether to expose properties and children of the value as properties and children.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
ifEmpty → String?: Description if the property description would otherwise be empty.
finalinherited
ifNull → String?: Description if the property value is null.
finalinherited
isInteresting → bool: Whether to consider the property's value interesting. When a property is uninteresting, its level is downgraded to DiagnosticLevel.fine regardless of the value provided as the constructor's level argument.
no setterinherited
level → DiagnosticLevel: Priority level of the diagnostic used to control which diagnostics should be shown and filtered.
no setterinherited
linePrefix → String?: Prefix to include at the start of each line.
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.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
showName → bool: Whether the name of the property should be shown when showing the default view of the tree.
finalinherited
showSeparator → bool: Whether to show a separator between name and description.
finalinherited
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.
no setterinherited
tooltip → String?: Optional tooltip typically describing the property.
finalinherited
unit → String?: Optional unit the value is measured in.
finalinherited
value → double?: Returns the value of the property either from cache or by invoking a ComputePropertyValueCallback.
no setterinherited

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 nonexistent method or property is accessed.
inherited
numberToString() → String: String describing just the numeric value without a unit suffix.
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.

Operators
