Flutter League

Flutter League is a companion app for League of Legends players that allows them to search for summoners, view their stats and match history, and check currently ongoing games.


The app consists of the following pages:

Home Page

The Home page is the first screen users see when they open the app. It displays information about the summoners that the user has saved as favorites. Users can select a League of Legends server and search for summoners.

Match History Page

The Match History Page displays a summoner's match history. It shows the summoner's rank, match history data, and provides the user with the option to load more matches.

Match Info Page

The Match Info page displays the details of a specific match, including the result, player stats, and team compositions.

Match Details Page

The Match Details page displays information about kills, gold, damage dealt, damage taken, wards, and CS in a TabView format.

Live Game Page

The Live Game page displays information about a currently ongoing League of Legends game, including player information and match details. It uses the DartLeagueRoleIdentify algorithm, available on GitHub at https://github.com/csuka1219/DartLeagueRoleIdentify, to identify the role for each player in the game.

The app uses the following dependencies:

There are still some features and improvements that could be made to this app. If you would like to contribute, please feel free to fork the repository and create a pull request. Here are some things that could be improved:

  • Add a message box to display the result when searching for a summoner that does not exist.
  • Add a message box to display the result when clicking on the "Live Game" button if there is no currently ongoing game.
  • Remove the display of players' roles in ARAM mode in the "Live Game" page.
  • There are some unsupported game modes such as "One For All".
  • You can implement any new features you desire.
