defaultTool property
      
      Tool
      get
      defaultTool
      
    
    
Gets or sets the default tool for this Diagram that becomes the current tool when the current tool stops. Initially this value is the same tool as #toolManager, which is an instance of ToolManager.
Setting this property also sets the #currentTool if the old default tool is the currently running tool.
Setting this property does not notify about any changed event. The value cannot be null and must not be shared with other Diagrams.
Implementation
_i3.Tool get defaultTool => _i4.getProperty(
      this,
      'defaultTool',
    );
      
      set
      defaultTool
      (Tool value) 
      
    
    
    
Implementation
set defaultTool(_i3.Tool value) {
  _i4.setProperty(
    this,
    'defaultTool',
    value,
  );
