Need to modify its source code:
The object OpenOfflineManager: MapMethodHandler {

Override fun with (map: AMap) : MapMethodHandler {
Return this
}
Override fun onMethodCall (methodCall: methodCall, methodResult: MethodChannel. Result) {
}
/* override fun onMethodCall (p0: MethodCall? P1: MethodChannel. The Result?) {

}

Also need to modify the source code:

Search. SetDistanceSearchListener {

result? . Success (list)
} else {
result? The error (" measuring failure code==& gt; $I ", null, null)
}
}

Fun Map ToLatlng () : LatLng {

Return LatLng (lat and LNG)
