Chess Puzzles game

I am looking for a developer to create a Chess Puzzles game for iOS, developed using Flutter. Create a Chess Puzzles game with predefined puzzles for the user to solve. A chess puzzle is a fixed position on a chess board, where there is a forced way to either checkmate or win considerable material. In a puzzle, the player gets either the white or the black pieces, and is asked to find the winning move(s). This game will include 50 puzzles, with more to be added later. The game is developed in Flutter, and will ultimately be built for iOS distribution. While testing, Android builds are accepted. Notable restrictions to the scope - The game will not include any AI or other algorithms to determine computer-play. A puzzle that consists of several moves will have the moves pre-defined, and there is only 1 correct solution to each puzzle. - The puzzles are predefined and delivered by the contractor. The developer does not need to come up with the puzzles. - All graphic assets are provided by the contractor. The project will include the following - Chess Puzzle data format - Chess Board setup and initialization - Method to determine all legal moves by the player - Player interaction with the board, highlighting possible legal moves - Gameplay for the user to complete puzzle, or move to the next - Always present a puzzle that the user has not yet completed. - Allow the user to get hints for the correct move Full specs are available and attached.
