Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.

Fast Development

Expressive and Flexible UI

Native Performance

(it's hot)

(ARM, dart compiler)

WIDGETS

Almost eveything in flutter is widget

Animations

Text

Layout

Gestures

Transition

SO,

IF EVERYTHING IN FLUTTER IS WIDGET.

WHAT ABOUT FLUTTER DEVELOPERS??

import './Bulgaa.dart'

import './Orgil.dart'

import './Baaska.dart'

import './Temuujin.dart'

WIDGET TYPE

STATEFUL

STATELESS

 Center(
      child: Text(
        'Hello, world!',
        textDirection: TextDirection.ltr,
      ),

import 'package:flutter/material.dart';

void main() {
  runApp(
    Center(
      child: Text(
        'Hello, world!',
        textDirection: TextDirection.ltr,
      ),
    ),
  );
}

DART

OOP?

import "dart:math" as math;
class Point {
  final num x, y;
  Point(this.x, this.y);
  Point.origin() : x = 0, y = 0;
   
  num distanceTo(Point other) {
   var dx = x - other.x;
   var dy = y - other.y;
   return math.sqrt(dx * dx + dy * dy);
  }
  
  Point operator +(Point other) => Point(x + other.x, y + other.y);
}

void main() {
  var p1 = Point(10, 10);
  var p2 = Point.origin();
  var distance = p1.distanceTo(p2);
  print(distance);
}

Just-in-Time (JIT)

Ahead-of-Time (AOT)

(in development)

(on release)

it compiles “only what is needed, when it is needed, and in the amount needed.

converts program source code into native machine code just before program execution

slower at startup, but it can have better peak performance after it runs long enough for runtime optimizations to be applied

Compiling your code before it is “delivered” to whatever runtime environment runs the code.

Fast startup and predictable performance of production deployments.
