PolygonPainterFillMethod enum

The method used by the painter to fill polygons and resolve overlaps & intersections

Each method has its own advantages and disadvantages.

Inheritance
Available extensions

Values

evenOdd → const PolygonPainterFillMethod

Uses PathFillType.evenOdd with Path().addPolygon

This gives the best performance, and works on the web. However, it yields unintended results in certain edge cases when polygons intersect when PolygonLayer.invertedFill is used, or when polygon holes intersect with other holes.

pathCombine → const PolygonPainterFillMethod

Uses Path.combine

This always gives the best results on non-web platforms. However, it always yields unintended results on the web (due to a Flutter issue), and has slightly worse performance.

The hit to performance is unlikely to be significant or even noticable in many applications, but applications drawing many polygons may see a slow of about 2ms (as tested in the example app's stress test). Profile your project to determine whether switching methods is suitable, especially if there is no visual difference.

See https://github.com/flutter/flutter/issues/124675 for the Flutter issue preventing this method from working on the web.
