Description

In this first tutorial, we build out the basic user interface for a minesweeper game using Flutter. First, we define the basic perimeters and rules of the game, minesweeper. We then use an Enum type to model the state of each of the tiles on our board. We use this state to build out a two dimensional list of this Enum. This two dimensional list allows us to programmatically generate the widgets required to create the board for our application.

Our Board is made up of nine rows, each filled with nine gesture detector widgets. Each of these tiles also contains a listener widget and a container. The container has the visual properties of the tile. These tiles are then pushed into each row which is then pushed into a single column widget. The column widget is then constrained by a container widget which allows us to pass back our board of eighty-one widgets as a single widget. This board is then embedded into our stateful widget which lets us see the visual outcome of the application.
