React Native geolocation: A complete tutorial

  1. Hello Emmanuel, just to help the other people going through this article. I noticed a small ‘possible modification’.
    When you mention the “getLocation” function in the finishing paragraph I found myself in a state of minute confusion. After checking the source code it makes sense that you have replaced that function with “permissionHandle”

  2. Thank you for reading the article Mushtaq! I do hope you found it useful. Thank you much more for pointing that out.

    1. The timestamp is based on the user location and returned from the `react-native-geolocation` library. It is calculated using the Date Time object. It is returned using `location.getTime()`. It is therefore not based on the telephone clock or cellular network.

  3. Thank you for this info! It runs on my device (via IntelliJ project ), but I keep receiving an error for the line:
    setLocation(posotion);

    It apparently only takes a boolean. But, more importantly, I cannot seem to find this function anywhere in the APIs I’ve searched.

    Any help with information on this function is very much appreciated.

    1. Solved. New to REACT (coming from low-level coding background and new to JS world). I located the setLocation reference. Though, I’m still confused on the initial boolean value instead of a position as the parm. Seems that the initial condition/default parm is taken as the type and IntelliJ gives a warning (yet all runs fine). I select option to ignore that warning but may be able to simply provide a position as default and then immediately set it to false once the initial function setup is complete.
