DoubleProperty class - foundation library

Constructors

DoubleProperty(String name, double value, { String ifNull, String unit, String tooltip, Object defaultValue: kNoDefaultValue, bool showName: true, 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

defaultValue → Object: If the value of the property equals defaultValue the priority level of the property is downgraded to DiagnosticLevel.fine as the property value is uninteresting. [...]
final, inherited
emptyBodyDescription → String: Description to show if the node has no displayed properties or children.
read-only, inherited
exception → Object: Exception thrown if accessing the property value threw an exception. [...]
read-only, inherited
hashCode → int: The hash code for this object. [...]
read-only, inherited
ifEmpty → String: Description if the property description would otherwise be empty.
final, inherited
ifNull → String: Description if the property value is null.
final, inherited
level → DiagnosticLevel: Priority level of the diagnostic used to control which diagnostics should be shown and filtered. [...]
read-only, inherited
missingIfNull → bool: Whether a value of null causes the property to have level DiagnosticLevel.warning warning that the property is missing a value.
final, inherited
name → String: Label describing the DiagnosticsNode, typically shown before a separator (see showSeparator). [...]
final, inherited
propertyType → Type: The type of the property value. [...]
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited
showName → bool: Whether the name of the property should be shown when showing the default view of the tree. [...]
final, inherited
showSeparator → bool: Whether to show a separator between name and description. [...]
final, inherited
style → DiagnosticsTreeStyle: Hint for how the node should be displayed.
final, inherited
textTreeConfiguration → TextTreeConfiguration: Returns a configuration specifying how this object should be rendered as text art.
@protected, read-only, inherited
tooltip → String: Optional tooltip typically describing the property. [...]
final, inherited
unit → String: Optional unit the value is measured in. [...]
final, inherited
value → double: Returns the value of the property either from cache or by invoking a ComputePropertyValueCallback. [...]

Methods

numberToString() → String: String describing just the numeric value without a unit suffix.
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() → Map<String, Object>: Serialize the node excluding its descendants to a JSON map. [...]
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
valueToString({TextTreeConfiguration parentConfiguration }) → String: Returns a string representation of the property value. [...]
inherited

Operators

operator ==(dynamic other) → bool: The equality operator. [...]
