    In flutter after null safety was enabled, you can’t leave a variable without assiging a value to it.
    you can either use late modifier, but you have to assign a value to it later

    late String textResult;

    or make it nullable using null check operator

    String? textResult;

    or just assign a value to it :

    String textResult = 'some text';
