Install Flutter Visual Studio Code Mac

  • Hello Friends, In this video tutorial, I will show you the flutter installation process in Visual studio code on Mac OS X Catalina. This process is very easy. Please follow the guidelines.
  • Android Studio Plugin Bump. Flutter complains that it can’t find something special in your Android Studio install even though you did it right. Flutter doctor keeps returning the same thing and you’re feeling icky. Flutter plugin not installed; this adds Flutter specific functionality. Dart plugin not installed; this adds Dart specific.
  • Install Flutter Extension on Visual Studio Code Launch Visual Studio code. Click on Extensions located in the left menu. Type flutter in the search bar.

The Dart and Flutter extensions extend VS Code with support for the Dart programming language and provides tools for effectively editing, refactoring, running, and reloading Flutter mobile apps, and AngularDart web apps.

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

Flutter In Visual Studio Code

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

Install Flutter Visual Studio Code Mac
  • 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
Studio

Creating Android Emulator

#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

Install Flutter Visual Studio Code Mac

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

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

Install Flutter Visual Studio Code Mac

#7 — How to Change App Icon

In Android

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

Code

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.

1- Article objective

In this article I'm going to show you how to create a simple Dart example on Visual Studio Code and run it successfully. First and foremost, make sure that you have already installed the​​​​​​​ Dart Code Extension in Visual Studio Code, otherwise you can refer to the following article:

Install Flutter Visual Studio Code Mac Os

Note that apart from Visual Studio Code, there are a lot of IDE(s) in support of Dart programming, such as Android Studio, IntelliJ IDEA,etc. Thus, the following articles may be useful for you:

2- The first Dart example with VS Code

After installing Dart Code Extension in Visual Studio Code, we will create an example of Dart and make sure that it runs perfectly on Visual Studio Code.
Firstly, create any folder, MyFirstDartProject,for example. Then open it with Visual Studio Code.
Now run the example:
After you press 'Run and Debug', the launch.json file will be created. It contains the configuration to specify the files used to run the application.
  • Run > Run Without Debugging
  • View > Debug Console
