This document details the steps to create a simple movie application using Flutter with data sourced from the TMDB API. It provides instructions on setting up a Flutter project, using necessary dependencies, and creating different components like movie lists and movie details screens. The document also includes code snippets for implementing the essential features of the app.

1. Project 1
Movie Apps
Pendahuluan
pada project 1 kali ini kita akan belajar bagaimana membuat movie apps sederhana
dengan menggunakan flutter, yang paling utama terlebih dahulu sudah mempunyai
akses API di website resmi https://www.themoviedb.org/?_dc=1586104474 karena kita akan
mengambil data berdasarkan API yang ada di web tersebut.
themoviedb.org
untuk mendapatkan API dari https://www.themoviedb.org/?_dc=1586104474m dan bagaimana cara
mengaksesnya bisa di baca link ini https://www.dicoding.com/blog/registrasi-testing-themoviedb-
api/ dengan mengikuti tutorial sederhana ini penulis mengharapkan pembaca dapat memahami
pemrograman flutter dan dapat dikembangkan menjadi lebih sempurna lagi.

2. New Project Flutter
ikuti langkah langkah berikut untuk dapat memulai project movie apps, pastikan sudah terinstall
flutter dan plugin flutter di pc maupun android studio.
Tampilan Awal Android Studio
Klik new flutter project

3. Ketikkan nama aplikasi
Klik Finish
siapkan library untuk request API http
buka situs resminya https://pub.dev/

4. lalu ketikkan library http di column search, buka tab installing copy http: ^0.12.0.4, kedalam
file flutter pubspec.yaml
name: fluttermovie
description: A new Flutter application.
# The following defines the version and build number for your
application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number
used as versionCode.
# Read more about Android versioning at https://developer.android.com/
studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while
build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/
Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.

# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec
# The following section is specific to Flutter.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like
this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific
"variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
lalu klik Pub Get(Android Studio) klik kanan Get Packages (Visual Code)
Ketikkan code di lib/main.dart
import 'package:flutter/material.dart';
import 'movie_list.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(

6. //Import movielist class
home: new MovieList(),

}
}
Lalu Buat file baru lib/config.dart
//API KEY
String getApiKey() {
return '6a5b06b76d2c628e345f4730e4473751';
}
File baru lib/movielist.dart
