of measurement.
Numeric formatting is optimized for debug message readability.

- 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 thevalue
(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, int wrapWidth = 65}) → 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 -
