you can set fallback is null don't worry it is return a empty container

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ConditionalBuilder(
        condition: false,
        builder: (context) => Center(child: Text('this is true')),
        fallback: null,
      ),
    );
  }

add a new function generateRandom(int min, int max); its return int , create random number between minimum and maximum

 int random = generateRandom(10 , 100);
//output 99 or 47 or 11 or else number
