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;
    }
