Hi Arjun,
the driver name is "GPKG". It should not be necessary to specify it, 
since it defaults to "GPKG" anyway.

Could you please specify what QGIS version exactly are you using?

Have you tried with a simpler code in the Python console?

filepath = "[complete file path and file name and extension (.gpkg)]
lyrname = "test_layer"
fields=QgsFields()
fields.append(QgsField("test_field", QVariant.Double))
opts = QgsVectorFileWriter.SaveVectorOptions()
writer = QgsVectorFileWriter.create(filepath, fields, QgsWkbTypes.Point, 
QgsCoordinateReferenceSystem("EPSG:4326"), 
QgsCoordinateTransformContext(), opts)
del writer

Please consider that the GeoPackage layer will be completely created 
only after the "del writer" instruction.

Best regards.
