hello_flutter

A new Flutter project.

Getting Started

This project is a starting point for a Flutter application.

A few resources to get you started if this is your first Flutter project:

• Lab: Write your first Flutter app
• Cookbook: Useful Flutter samples

For help getting started with Flutter, view our online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.

Notes

• Every widget is a dart class that has a build method

• use named arguments if you don't have to remm=emeber the position of each argument

• because names arguments are optional you can assign default values

• @required can be used in flutter to ensure a that a named variable is provided

• A constructor runs once the class is called

• Normal class

  Person({String inputName = "Max", int inputAge = 30}) {
  name = inputName;
  age = inputAge;
  }

• Class with constructor

  class Person {
  String name;
  int age;


  Person(
  {this.name = "Max",
  this.age = 30}); // this will immediately update the value
  }

  var newPerson = Person(
  name: 'alabao',
  age: 3,
  );`

• You can user function short hand as void main() => runApp(myApp())

• Add leading underscore to make a private property _MyApp

• Adding const before variables means that you cannot modify the value of the variable. eg, if a var is equally to an object tith 1 item you can't chnage it to 2 items

  var hello = const ['name']

  hello.add('mac') // this will through and error

  hello = [] // this will work because you are not trying to modify the list

• Use getters to return a value, online functions it cannot accept any value

 String get ResultPhrase {
    return 'meat'
  }
