TextTreeConfiguration constructor

TextTreeConfiguration({@required String prefixLineOne, @required String prefixOtherLines, @required String prefixLastChildLineOne, @required String prefixOtherLinesRootNode, @required String linkCharacter, @required String propertyPrefixIfChildren, @required String propertyPrefixNoChildren, String lineBreak: '\n', bool lineBreakProperties: true, String afterName: ':', String afterDescriptionIfBody: '', String beforeProperties: '', String afterProperties: '', String propertySeparator: '', String bodyIndent: '', String footer: '', bool showChildren: true, bool addBlankLineIfNoChildren: true, bool isNameOnOwnLine: false, bool isBlankLineBetweenPropertiesAndChildren: true })

Create a configuration object describing how to render a tree as text.

All of the arguments must not be null.
