initState method

@override void initState()

Called when this object is inserted into the tree.

The framework will call this method exactly once for each State object it creates.

Override this method to perform initialization that depends on the location at which this object was inserted into the tree or on the widget used to configure this object.

• In initState, subscribe to the object.

Here it overrides to initialize the object that depends on rendering the SfPyramidChart.

Implementation

@override
void initState() {
  _stateProperties = PyramidStateProperties(
      renderingDetails: RenderingDetails(), chartState: this);

  _initializeDefaultValues();
  //Update and maintain the series state, when we update the series in the series collection //
  _createAndUpdateSeriesRenderer();
  super.initState();
}
