Getting Started

dependencies:
  conditional_builder_null_safety: ^0.0.6

import this package

import 'package:conditional_builder_null_safety/conditional_builder_null_safety.dart';

Example

If the condition is true, will be builder executed

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: ConditionalBuilder(
          condition: true,
          builder: (context) => Center(child: Text('this is true')),
          fallback: (context) => Center(child: Text('this is not true')),
        ),
      ),
    );
  }

If the condition is not true or false, will be fallback executed

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ConditionalBuilder(
        condition: false,
        builder: (context) => Center(child: Text('this is true')),
        fallback: (context) => Center(child: Text('this is not true')),
      ),
    );
  }

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
