keepViewportWithinData property

@override bool get keepViewportWithinData

Keeps the scale and translate sane if true (default).

Setting this to false disables some pan/zoom protections that prevent you from going beyond the data extent.

Implementation

@override
bool get keepViewportWithinData => _viewportSettings.keepViewportWithinData;

@override set keepViewportWithinData (bool autoAdjustViewportToNiceValues)

Implementation

@override
set keepViewportWithinData(bool autoAdjustViewportToNiceValues) {
  _scaleReady = false;
  _viewportSettings.keepViewportWithinData = true;
}
