    You need to add the file to your solution. Then make sure the file Build Action is MauiAsset.

    Then you can use the file as the following , the filename is a constant in this case.

        public async static Task<string> GetHistTeams()
        {
            string txt;
            string mainDir = FileSystem.Current.AppDataDirectory;
            var fullpath = Path.Combine(mainDir, "theTeams.json");
    
            try
            {
                Stream fileStream = await FileSystem.Current.OpenAppPackageFileAsync("theTeams.json");
                StreamReader reader = new StreamReader(fileStream);
    
                txt = reader.ReadToEnd();
            }
            catch (Exception e)
            {
                var i = 1;
                return string.Empty;
            }
            return txt;
        }
