I want to be able to open Google maps app from my app and get directions with multiple waypoints from my apps data.
If you check this libraryr react-native-directions . . There you can provide the lat , long and it will open the maps with . directions. Under the hood it only calls Linking
of react-native
with
const url = `https://www.google.com/maps/dir/?api=1&${getParams(
params
)}${getWaypoints(waypoints)}`
So you can either do it like this or use the library.
Hope it helps. feel free for doubts
