viewportScalingFactor property

  1. @override
double viewportScalingFactor

Returns the current viewport scale.

A scale of 1.0 would map the data directly to the output range, while a value of 2.0 would map the data to an output of double the range so you only see half the data in the viewport. This is the equivalent to zooming. Its value is likely >= 1.0.

Implementation

@override
double get viewportScalingFactor => _viewportSettings.scalingFactor;
