groupTemplateMap property
Gets or sets a Map mapping template names to Groups. These groups are copied for each group data that is added to the #model.
The new value must not be null, nor may it contain a Node or Link or simple Part. The Links must not be in the visual tree of any Diagram. Replacing this Map will automatically call #rebuildParts.
If you modify this Map, by replacing a Group in it or by adding or removing a map entry, you need to explicitly call #rebuildParts afterwards.
Implementation
_i3.Map<_i2.String, _i3.Group> get groupTemplateMap => _i4.getProperty(
this,
'groupTemplateMap',
);
