For ranging result, beacons is a List of Beacon's object. You need to learn about how to get data from a list by referring to List class docs here.

Hi, I try to create a variable like this final _major = result.beacons[].major but I don't understand what is an index of desired beacon.
I try this line final _major = result.beacons[].major
I try add this line with other variable
class _MyAppState extends State
{
StreamSubscription _streamRanging;
final _beacons = [];
final _major = result.beacons[].major;
....
} but there are an issue with result which does not existe
I try add my line in
_streamRanging = flutterBeacon.ranging(regions).listen
((result)
{
result.beacons.forEach
((b)
{
final _major = result.beacons[].major;
print(b.major);
_beacons.sort(_compareParameters);
monid =b.major;
print('monid=');
print(monid);
return b.major;
}
);
}
); with this code the issue is "The argument type 'List' can't be assigned to the parameter type 'int'"
my goal it's take the major and put it in a variable. But I am a beginner in flutter , can you help please
