I have trouble to use function dissolve to dissolve polygons by field value in PyQGIS3. In PyQGIS2 this line was doing the job:
QgsGeometryAnalyzer().dissolve(ki, "name.shp", onlySelectedFeatures=False,uniqueIdField=-1, p=None)
I read on this site that processing alg should be use in PyQGIS3. But I can't find here disolve. When I run
processing.algorithmHelp("native:dissolve") I can't get the list of attributes, I just get some basic information. So I don't know how to use it.
