How to Install Flutter on Windows?

Minimum System Requirements

• Operating Systems: Windows 7 or later [64-bit]
• Disk Space: 400 MB
• Git for Windows
• Flutter SDK 2.10.5-stable

Get the Flutter SDK

• Download Flutter SDK HERE
• Unzip the downloaded zip in C:\flutter .
• Locate flutter_console.bat inside the flutter directory and start it by double-clicking.

Update your path

If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the PATHenvironment variable:

• From the Start search bar, type ‘env’ and select Edit environment variables for your account
• Under User variables check if there is an entry called Path:
• If the entry does exist, append the full path to flutter\bin using ; as a separator from existing values.
• If the entry does not exist, create a new user variable named Path with the full path to flutter\bin as its value.

Note that you will have to close and reopen any existing console windows for these changes to take effect.

Run flutter doctor

From a console window which has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:

C:\flutter>flutter doctor

This command checks your environment and displays a report of the status of your Flutter installation. Check the output carefully for other software you may need to install or further tasks to perform (shown in bold text).

For example:

[-] Android toolchain - develop for Android devices
• Android SDK at C:\Android\sdk
✗ Android SDK is missing command line tools; download from https://goo.gl/XxQghQ
• Try re-installing or updating your Android SDK,
visit https://flutter.dev/setup/#android-setup for detailed instructions.

Android Setup

Flutter relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Flutter apps in a number of editors.

Install Android Studio

• Download and install Android Studio.
• Start Android Studio, and go through the ‘Android Studio Setup Wizard’. This installs the latest Android SDK, Android SDK Platform-Tools, and Android SDK Build-Tools, which are required by Flutter when developing for Android.

Set up your Android device

To prepare to run and test your Flutter app on an Android device, you’ll need an Android device running Android 5.0 (API level 21) or higher.

• Enable Developer options and USB debugging on your device. Detailed instructions are available in the Android documentation.
• Windows-only: Install the Google USB Driver
• Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device.
• In the terminal, run the flutter devices command to verify that Flutter recognizes your connected Android device.

By default, Flutter uses the version of the Android SDK where your adb tool is based. If you want Flutter to use a different installation of the Android SDK, you must set the ANDROID_HOME environment variable to that installation directory.

Install the Flutter and Dart plugins

• Start Android Studio.
• Open plugin preferences (File > Settings > Plugins).
• Select Browse repositories, select the Flutter plugin and click Install.
• Click Yes when prompted to install the Dart plugin.
• Click Restart when prompted.

How to Install Flutter on MacOS?

Minimum System Requirements

• Operating Systems: macOS [64-bit]
• Disk Space: 700 MB
• Git for macOS
• Flutter SDK 2.10.5-stable
• Download Latest Flutter SDK HERE
• Extract the file in the desired location e.g.



cd ~/development
unzip ~/Downloads/flutter_macos_v1.5.4-hotfix.2-stable.zip


• Add the flutter tool to your path. To do this, open your bash profile from your terminal (might need sudo)

sudo vim ~/.bash_profile

Add your flutter path to the $PATH variable in bash_profile.

E.g. If you extracted flutter in your Applications folder, your path will be /Applications/flutter/bin . Add this to the existing $PATH variable by using : in between two paths. Once added, save and close the bash_profile . Run terminal again and check the $PATH by running

echo $PATH

You should see your Flutter path added to the $PATH

Run flutter precache in the terminal.

Run flutter doctor

Run the following command to see if there are any dependencies you need to install to complete the setup (for verbose output, add the -v flag):

flutter doctor

This command checks your environment and displays a report to the terminal window. The Dart SDK is bundled with Flutter; it is not necessary to install Dart separately. Check the output carefully for other software you may need to install or further tasks to perform (shown in bold text). For example: If you haven’t used Flutter before, you might see an output like this by running flutter doctor You can see there are several things to be done to begin using Flutter in this Mac. To correct these issues, let’s run following commands

Fix license issue in Android studio

$ brew update
$ brew install --HEAD usbmuxd
$ brew link usbmuxd
$ brew install --HEAD libimobiledevice
$ brew install ideviceinstaller


Update iOS-deploy

npm install -g ios-deploy

iOS Setup

Install Xcode

To develop Flutter apps for iOS, you need a Mac with Xcode 9.0 or newer:

• Install Xcode 9.0 or newer (via web download or the Mac App Store).
• Configure the Xcode command-line tools to use the newly-installed version of Xcode by running the following from the command line:



sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

• This is the correct path for most cases, when you want to use the latest version of Xcode. If you need to use a different version, specify that path instead.
• Make sure the Xcode license agreement is signed by either opening Xcode once and confirming or running sudo xcodebuild -license from the command line.

With Xcode, you’ll be able to run Flutter apps on an iOS device or on the simulator.

Set up the iOS simulator

To prepare to run and test your Flutter app on the iOS simulator, follow these steps:

• On your Mac, find the Simulator via Spotlight or by using the following command:

open -a Simulator

• Make sure your simulator is using a 64-bit device (iPhone 5s or later) by checking the settings in the simulator’s Hardware > Device menu.
• Depending on your development machine’s screen size, simulated high-screen-density iOS devices may overflow your screen. Set the device scale under the Window > Scale menu in the simulator.

Android Studio — Install Flutter and Dart plugins

• Start Android Studio.
• Open plugin preferences (Preferences > Plugins on macOS, File > Settings > Plugins on Windows).
• Select Browse repositories, select the Flutter plugin and click Install.
• Click Yes when prompted to install the Dart plugin.
• Click Restart when prompted.

After opening the project in Android studio. Select terminal from bottom, type this command and hit enter.

Change App Language

For adding new language , you need to add a file for example you want to add french so your file name should be fr_FR.dart. Check the language code from here

Make a copy of the file en_US.dart inside lib/AppConfig/language/languages folder.

Now open the file and modify the file.

See below image, here we store data as "key":"value" pair ( "Home": "Home",) so make sure that you dont change key , always change value(right side string)

Make sure to change en_US to your language code from line number 1. For example if your language is french, then put fr_FR here.

• Now open lib/language/translation.dart file and add the newly added file.
For example if your language file is fr_FR.dart then add this line after line number 6
import 'languages/fr_FR.dart';

• After that copy this 'en_US': en_US, line and paste on the next line. (Enter and paste)
The line should be exacly like this for your language-
'fr_FR': fr_FR,

• After that copy the marked lines and paste on the next line. (Enter and paste)
The lines should be exacly like this for your language-
else if (language == 'fr_FR') {
LanguageSelection.instance.val = 'fr_FR';
LanguageSelection.instance.drop = 'fr_FR';
appLocale = 'fr_FR';
}

• After that scroll down and copy the marked lines and paste on the next line. (Enter and paste)
The lines should be exacly like this for your language-
LanguageModel(
languageText: 'French',
languageValue: 'fr_FR',
),
Language name on languageText and language code that your added on earlier is the languageValue

Remember just change the language code strings. Everything else remains the same.

Setup Social Login

Google Login

Before add google login to your flutter app, you need to create a firebase project to connect to your app.

At first create project at firebase

Go to https://console.firebase.google.com and create a project. Give a project name.

Create Android app

The "Android package name" must match your local project's package name that was created when you started the Flutter project. The current package name can be found in your module (app-level) Gradle file, usually android/app/build.gradle, defaultConfig section (example package name: com.yourcompany.yourproject).

Once your Android app has been registered, download the configuration file from the Firebase Console (the file is called google-services.json). Add this file into the android/app directory within your Flutter project.

Create iOS app

On the Firebase Console, add a new iOS app or select an existing iOS app for your Firebase project. The "iOS bundle ID" must match your local project bundle ID. The bundle ID can be found within the "General" tab when opening ios/Runner.xcworkspace with Xcode.

Download the GoogleService-Info.plist file for the Firebase app.

Next you must add the file to the project using Xcode (adding manually via the filesystem won't link the file to the project). Using Xcode, open the project's ios/{projectName}.xcworkspace file. Right click Runner from the left-hand side project navigation within Xcode and select "Add files", as seen below:

Select the GoogleService-Info.plist file you downloaded, and ensure the "Copy items if needed" checkbox is enabled:

Open amazcart_app > ios > Runner > Info.plist file

Change REVERSED_CLIENT_ID in Google login option

If you want you may go through this link firebase(android/ios) documentation

Facebook Login

• Go to amazcart_app > lib folder > AppConfig folder > app_config.dart > then set facebookLogin to true

Android Setup

Go to -> Facebook Login for Android - Quickstart



To find info to how to generate you key hash go to this link Note: if your application uses Google Play App Signing then you should get certificate SHA-1 fingerprint from Google Play Console and convert it to base64 You should add key hashes for every build variants like release, debug, CI/CD, etc.

iOS Setup

Go to -> Facebook Login for iOS - Quickstart



Open amazcart_app > ios > Runner > Info.plist file

Change FacebookAppID,FacebookClientToken,FacebookDisplayName strings
