Go to the Menu which will appear at the right hand side. Then, click "Pokemon". Select the Pokemon that knows Flash, click on it and the following options will come up:


Click Flash, and the Granite Cave will light up.

Don't forget that you need to have the Gym Badge from Brawly too.
Oh yep, thanks!
