Description

Instead of returning result from onSuccess param, getCurrentPosition returns immediately with undefined, and callback is called afterwards.

Reproducible Demo

const test = async () => {
    console.log("Starting test");
    const result = await getCurrentPosition(
        (position) => {
            console.log("Got position");
            return true;
        },
    );
    console.log("Finishing test, result:", result);
);

Expected Results

Expected logs:

Starting test
Got position
Finishing test, result: true

Actual logs:

Starting test
Finishing test, result: undefined
Got position

Closing this as latest version contains the proper typings.

Actually, getCurrentPosition is async (returns a Promise) in the version I have (2.0.2). At least that’s what index.d.ts is describes it as. Lines 61-65:

  export function getCurrentPosition(
    successCallback: SuccessCallback,
    errorCallback?: ErrorCallback,
    options?: GeoOptions
  ): Promise<GeoPosition>

In any case, I decided to do a workaround to get it to work as I need it to. Here it is, in case anyone is in the same situation:

const getLocation = (onSuccess, onError, options) => new Promise((resolve, reject) => {
  Geolocation.getCurrentPosition(
    (result) => resolve(onSuccess(result)),
    (error) => reject(onError(error)),
    options,
  );
});
