[QGIS-Developer] PyQGIS : Creating a Geopackage layer without adding features

[René-Luc Dhont]

Hi Devs,

I have tested this and it works
from qgis.core import QgsVectorLayer, QgsVectorFileWriter
ml = QgsVectorLayer('Point?field=firstfield:int&field=secondfield:int', 
'test', 'memory')
filename = '/tmp/testing.gpkg'

options = QgsVectorFileWriter.SaveVectorOptions()
options.driverName = 'GPKG'
options.layerName = 'test'
write_result, error_message = 
QgsVectorFileWriter.writeAsVectorFormat(ml,filename,options)
write_result == QgsVectorFileWriter.NoError
