But in my android folder shows unused dependencies . Anyone can explain this and how to remove this from project ? Ex:package_info_plus

My flutter app run well, but when I try to upload the app to App Store by archive it: Xcode -> Product -> Archive
it failed and get two errors First one in flutter_inappwebview with following error message:

I am facing a null safety issue in Text( "Latitude: " + currentPosition.latitude.toString(), ) this line. i dont know how to make currentPosition.latitude not null help me with this guys.

It gives me this The property 'latitude' can't be unconditionally accessed because the receiver can be 'null'. Try making the access conditional (using '?.') or adding a null check to the target ('!'). error.

The property 'longitude' can't be unconditionally accessed because the receiver can be 'null'. Try making the access conditional (using '?.') or adding a null check to the target ('!'). error

I'm looking for little help with this code, I'm simply trying to get he High Accuracy Lon and Lat, but it keeps coming out with 0.0

What am I missing?

I want to put extra data at node in database this node is created using geofire and when i try to put this information is appear at database then hide like below,

I have Geolocator package that I am using to gain users current location. This is returned in lat,long format.

I am now calling an API and the bounding box is a parameter in the URL. I want to take a certain area around their current location, making users location the centre point of the bounding box.

Bounding Box needs min (Longitude, latitude ) & max(longitude, latitude).

I don't know how to calculate that and can't find much online to help out.

I can access their location from Firestore. What I need is to be able to convert the data from Firestore into dart language. Then I have to do the listing Firestore locations from closest to farthest. This is my Firestore:

This is my code:

I do not know what went wrong but each time i tried to run this code in on the emulator it shows an error in the terminal and won't run, but once i choose chrome as the testing device it works smoothly , i am trying to use the geolocator package from pub.dev

my code:
