DiagnosticsBlock class
DiagnosticsNode that exists mainly to provide a container for other diagnostics that typically lacks a meaningful value of its own.
This class is typically used for displaying complex nested error messages.

DiagnosticsBlock({String? name, DiagnosticsTreeStyle style = DiagnosticsTreeStyle.whitespace, bool showName = true, bool showSeparator = true, String? linePrefix, Object? value, String? description, DiagnosticLevel level = DiagnosticLevel.info, bool allowTruncate = false, List<
DiagnosticsNode> children = const <DiagnosticsNode>[], List<DiagnosticsNode> properties = const <DiagnosticsNode>[]}) -
Creates a diagnostic with properties specified by
propertiesand children specified bychildren.
Properties
- allowNameWrap → bool
-
Whether to wrap the name onto multiple lines or not.
no setterinherited
- allowTruncate → bool
-
Whether to allow truncation when displaying the node and its children.
final
- allowWrap → bool
-
Whether to wrap text on onto multiple lines or not.
no setterinherited
- emptyBodyDescription → String?
-
Description to show if the node has no displayed properties or children.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- level → DiagnosticLevel
-
Priority level of the diagnostic used to control which diagnostics should
be shown and filtered.
final
- linePrefix → String?
-
Prefix to include at the start of each line.
finalinherited
- name → String?
-
Label describing the DiagnosticsNode, typically shown before a separator
(see showSeparator).
finalinherited
- 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
- value → Object?
-
The actual object this is diagnostics data for.

Methods
-
getChildren(
) → List< DiagnosticsNode> -
Children of this DiagnosticsNode.
override
-
getProperties(
) → List< DiagnosticsNode> -
Properties of this DiagnosticsNode.
override
-
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
-
toDescription(
{TextTreeConfiguration? parentConfiguration}) → String -
Returns a description with a short summary of the node itself not
including children or properties.
override
-
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).

Operators
-
operator ==(
Object other) → bool -
The equality operator.
