Fletchinder evolves from Fletchling starting at level 17 and then evolves into Talonflame starting at level 35. This evolution path applies in various Pokémon games including Pokémon Scarlet and Violet as well as other generations. So, to get a Fletchinder, you need to level up a Fletchling to at least level 17, and to evolve Fletchinder into Talonflame, you must level it up further to level 35.
