Flutteris an open source mobile app development SDK from Google, used to build beautiful Native Android and iOS apps with a single codebase. Dart is the language used to develop Flutter apps.

Flutter is now out of beta andFlutter 1.0 was announced on Dec 4th.

This article covers how to install Flutter and the development environment, and also shares solutions for the most common requirements and issues faced in Flutter app development. The process below is more helpful for Android developers who want to try their hand at Flutter app development.

#1 —Setup

‍

IDEs used to develop Flutter apps

Installation of Flutter

Download Flutter Zip file.
Extract Zip file.
Add Flutter tool to the path from the terminal.
$ export PATH = $PATH: 'PWD'/flutter/bin
PWD → Present Working Directory.
This is a temporary path setting, so when you restart your system, you have to set the Flutter tool path again.

‍

Note: To set the Flutter path permanently in MacOS and avoid setting on every restart, do as shown below in your MacOS terminal.

‍

touch .bash_profile
open .bash_profile
$ export PATH=$PATH: 'PWD'/flutter/bin
“PWD” → Present Working Directory.

‍

To verify Flutter installation and version

flutter doctor -v

#2— Android Studio Configuration

‍

Installation of Android Studio

‍

To run the app in Android Emulator, you must install Android Studio to get the Android SDK and emulators.

Download Android Studio and run the .dmg file. It will automatically install the latest Android SDK.

‍

Add Dart Plugin to Android Studio

If you prefer to use Android Studio as your main IDE to develop Flutter, you have to set dart language support to Android Studio as shown below. From here we will be focusing more on Android Studio setup, but you could also use Visual Studio Code or IntelliJ (which is similar to Android Studio).

Preferences → Plugins → Browse Repository → type Dart in search bar → Install and Restart Android Studio.

‍

Add Flutter Plugin to Android Studio

Preferences → Plugins → Browse Repository → type Flutter in search bar → Install and Restart Android Studio.

‍

Create Android Emulator

Tools → AVD Manager → Opens a window
Select → Create Virtual Device
Phone → Nexus 5X 5’2″ → Oreo x86 → Android 8.0 → AVD Name(Nexus 5X API 26) → Finish
Select Nexus 5X API 26 emulator → click on Launch AVD(start) button

‍

#3— iOS Simulator Setup

‍

Installation of Xcode

To execute the app in iOS simulator, we must install Xcode. Get Xcode from App Store and install.

‍

Launch iOS Simulator from Android Studio

You can see the Flutter Device Selection button below the toolbar in Android Studio.
If you have already installed Xcode, clicking the Flutter Device Selection button opens the iOS simulator.

‍

Useful iOS Simulator Commands

Return to Home → Cmd+Shift+h
See Recent Apps →Cmd+Shift+h+h
Quit Simulator→Cmd+q

‍

#4—Using Terminal to Run on Emulator or Simulator

‍

Execute Flutter Apps from Terminal

Run From Terminal → flutter run
Run in all devices → flutter run -d all lib/welcome.dart

‍

If your system is connected with multiple devices then, check the connected devices with this command → flutter devices

‍

Running above command will list devices like below

SM G890UU • 4299a0c86788f678 • android-arm • Android 7.0 (API 24) (emulator)

‍

Run in the selected device → flutter run -d 4299a0c86788f678

Check the specific design/run particular dart file in a selected device → flutter run -d 4299a0c86788f678 lib/main.dart

‍

#5 — Flutter Project Structure

In this article, I am using Flutter with Android Studio.

‍

Flutter Project Structure

In the Project section, the above screenshot shows the structure of the Flutter app.

‍

android: Has all the Android related files.
iOS: Has all the iOS-related files.
lib: Has all the dart files. This is the main folder, where we can write all the application code.
test: Has all the testing code.
images: I created this folder. This has all the images we used in our application.
pubspec.yaml: Has all the third party dependencies and the assets we use in our application.
yaml — Yet Another MultiColumn Layout.

‍

Add dependencies and images in pubspec.yaml file

flutter_rating is the third party dependency.
We have to specify assets in the pubspec.yaml. We can
specify file path with folder name and file name or only the folder name.

images/apple.jpeg → we can use only apple.jpeg image.
images/ → we can use all images that are in the images folder.

Make sure that dependencies are properly aligned with spaces. Otherwise, the images won’t display. This particular issue is hard to figure out if you are fairly new to Flutter or YAML.

#6 — How to Change App Name

‍

In Android

‍

Android folder → app → src → main → Open Manifest → change the label in Application tag.

android:name=”io.flutter.app.FlutterApplication”
android:label=”flutter_android_app”/>

‍

In iOS

‍

iOS folder → Runner → info.plist → Edit the string under CFBundleName

<key>CFBundleName</key>
<string></string>flutter_ios_app

‍

#7 — How to Change App Icon

‍

In Android

‍

Expand the Android folder → app → src → main → res → add app icons in mipmap folders.

‍

Expand the Android folder → app → src → main → open Manifest → change the icon in Application tag.

android:name=”io.flutter.app.FlutterApplication”
android:label=”flutter_android_app”
android:icon=”@mipmap/ic_launcher”>

‍

In iOS

‍
Expand iOS folder → Runner → Assets.xcassets → AppIcon.appiconset
In that folder add all app icons.

‍

Expand iOS folder → Runner → Assets.xcassets → AppIcon.appiconset → update the Contents.json file.

‍

#8 — How to change Splash Image

‍

In Android

‍

Expand Android folder → res → drawable → add image
Expand Android folder → res → drawable → in Launch_background.xml, add bitmap tag.

<item></item>
android:gravity=”center”
android:src=”@drawable/ios_android” />

‍

In iOS

‍

Expand iOS folder → Runner → Assets.xcassets → LaunchImage.imageset → add all sizes of splash images in the folder

Expand iOS folder → Runner → Assets.xcassets → LaunchImage.imageset → → open Contents.json → change file name

‍

I hope the above setup instructions and advice on how to set a few basic requirements are useful for beginners in Flutter app development. As Flutter is now out of beta, I look forward to seeing more and more developers using Flutter for developing Android and iOS apps with a single codebase. For motivation, check out this Widgets Library website built by the Flutter community.

Made by

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

Coming from another platform? Docs: iOS, Android, Web, React Native, Xamarin.

Fast Development

Paint your app to life in milliseconds with Stateful Hot Reload. Use a rich set of fully-customizable widgets to build native interfaces in minutes.

Expressive and Flexible UI

Quickly ship features with a focus on native end-user experiences. Layered architecture allows for full customization, which results in incredibly fast rendering and expressive and flexible designs.

Native Performance

Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts, and your Flutter code is compiled to native ARM machine code using Dart's native compilers.

Fast development

Flutter's hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times without losing state on emulators, simulators, and hardware.
