When I run the following in a plugin I get

name 'QgsLayerTreeLayer' is not defined

print('Loading raster layer...')

                            #QgsProject.instance().removeMapLayer(tLayer)

                            print("%s called %s" % (filePath, fname))

                            tLayer = QgsRasterLayer(filePath, fname, 'gdal')

                            QgsProject.instance().addMapLayer(tLayer, False)

                            print('layerTreeCanvasBridge')

                            layerTree = iface.layerTreeCanvasBridge().rootGroup()

                            print(layerTree)

                            layerTree.insertChildNode(-1, QgsLayerTreeLayer(tLayer))

However in python console it works

filePath=r'c:resourceslandcover.img'

tLayer = QgsRasterLayer(filePath, 'imagery', 'gdal')

layerTree.insertChildNode(-1, QgsLayerTreeLayer(tLayer))

The plugin imports

from qgis.core import QgsApplication, QgsVectorLayer, QgsRasterLayer, QgsProject 

from qgis.utils import iface

Should I import something else? This is based on https://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/loadlayer.html
