TextTreeConfiguration class Null safety
Configuration specifying how a particular DiagnosticsTreeStyle should be rendered as text art.
In release mode, these configurations may be ignored, as diagnostics are compacted or truncated to save on binary size.
See also:
- sparseTextConfiguration, which is a typical style.
- transitionTextConfiguration, which is an example of a complex tree style.
- DiagnosticsNode.toStringDeep, for code using TextTreeConfiguration to render text art for arbitrary trees of DiagnosticsNode objects.
Constructors

no children.
final
- afterDescription → String
-
Text to add immediately after the description line of a node with
properties and/or children.

final
- bodyIndent → String
-

-
Whether to place line breaks between properties or to leave all
properties on one line.
final
- linkCharacter → String
-
Character to use to draw line linking parent to child.
final

whether the node has any properties.
final
-
Footer to add even for root nodes.
final
- prefixLastChildLineOne → String
-
Prefix to add to the first line to display the last child of a node with
this style.
final
- prefixLineOne → String
