There are many IDEs to develop mobile applications but I recommend you choose anyone from below.

- Flutter applications are not just Dart, however. Since the agency is a contractor developing this application for the Fortune 500 firm, and since the application is not an open source project, the agency cannot use Visual Studio Community 2019for developing and testing the application.
- Alternatively, you can use a combination of the flutter command in a terminal and one of the many editors that support editing Dart.
Flutter is the next generation easy app development framework for mobile apps (Android and iOS), desktop app, and web apps. Here some extension in Visual Studio Code that is useful for cross platform application development with Flutter Framework.
- Visual Studio Code
- Android Studio
The reason for recommending these two IDEs is their high performance and rich functionality.
This Flutter tutorial teaches you how to create a new Flutter project using Visual Studio Code.
Create A New Flutter Project In Visual Studio Code
To download and install the Visual Studio Code check the link
After you have successfully installed the Visual Studio Code into your computer. Russell brand booky wook. Now follow the steps as mentioned below.
- Open the Visual Studio Code.
- On the left sidebar locate option number 4 which is named as extensions. Click on it.
- In the search bar, you have to download three extensions. Flutter, Dart and Material Icon Theme.
- Another extension name is “Awesome Flutter Snippets” that you should download and install as well.
After you have done all the above steps now you are ready to create your new Flutter project in Visual Studio Code.
Now I will teach you how to create your Flutter project in VS Code.
- Click on the View tab in the menu bar and select Command Palette. Shortcut Ctrl + Shift + p.
- Now type Flutter you will see many different options.
- Select the option as Flutter: New Project. Give your project any valid name just as MyApp and press enter.
- Choose the parent directory where you want your app to be stored in your machine.
- Now, wait for a few moments to the VS Code to create your new Flutter project with all the default files and codes.
- The file in which you work most of the time is the main.dart file.
Note:When you create a new Flutter application your IDE requires you to enter a company domain name in reverse order. Reverse order use to maintain the uniqueness of your app on the Google App Store. This company domain name can’t change once it is set.
How To Run Your New Flutter App In VS Code
To run your newly created Flutter project follow the steps below.
On your VS Code and locate the status bar with blue color at the very bottom.
After selecting your emulator to run your app open your main.dart file in the lib folder.
Click on the Debug -> Start Debugging or press F5.
Your app will be launch after a few moments.
The the debugging is complete your app will look like this.
Hot Reload In Flutter Flutter
Hot Reload is a great feature of Flutter. It makes the development cycle much faster. With Hot Reload if you make any changes in your code you can see the results almost instantly.
Let’s have a look at Hot Reload.
Change the piece of string

with this one Hp easy scan.
now save your code and you can see the changes in not time on your simulator or device.
Congratulations! Now you are ready to create and run your Flutter Application in the Visual Studio Code without any error.
VS Code extension to create a binding between your translations from .arb files and your Flutter app. It generates boilerplate code for official Dart Intl library and adds auto-complete for keys in Dart code.
This plugin is also available for IntelliJ / Android Studio.
CLI tool intl_utils can be used for manual invocation or in CI/CD systems.

Getting started
1. Install the VS Code extension
Install from the Visual Studio Code Marketplace or by searching within VS Code.
2. Initialize extension for your project
Open your project, open the command palette and find the
Flutter Intl: Initialize
command.By default
en
locale is added by auto-creating a file lib/l10n/intl_en.arb
.NOTE: By default the extension generates and maintains files inside
lib/generated/
folder which you should not edit manually. But you should keep these files in your project repository.3. Setup your app
Add dependency needed for localization:
Setup your
localizationsDelegates
and your supportedLocales
which will allow to access the strings.Additional set up for iOS apps:
To enable localization for iOS apps, extend
ios/Runner/Info.plist
file with supported locales configuration.This list should be consistent with the locales listed in the lib/l10n
folder.Current locale can be changed programmatically using
S.load
method and passing the locale:Access to the current locale:
4. Add other locales
You probably want to localize you Flutter app into more than one locale.
You can add more locales with command
Flutter Intl: Add locale
.5. Add keys to main ARB file
ARB files extension stands for Application Resource Bundle and is used by the Dart Intl package. It's supported by Google and is official localization library for Dart.
File content example:
In the example above we have 5 keys:
pageHomeConfirm
- A very simple keypageHomeWelcome
- A key which translation contains a placeholdername
pageHomeWelcomeGender
- A gender key whose translation depends on a placeholdergender
. Genders are formatted in ICU format.pageHomeWelcomeRole
- A select key whose translation depends on a placeholderrole
. Selects are formatted in ICU format.pageNotificationsCount
- A plural key whose translation depends on a placeholderhowMany
. Plurals are formatted in ICU format.
Your main ARB file by default is
lib/l10n/intl_en.arb
. When you add new key-value pairs in it and save the file, those keys will be automatically available for auto-complete in your Dart code.6. Reference the keys in Dart code
The ARB file's keys now correspond to methods from the
S
class. For example:In case keys have defined placeholders, or their translation is in Plural, Gender or Select ICU format, you can reference them in your code in a following way:
By default the extension recognizes placeholders order by how they are defined in the main ARB file for that key. If you want to redefine the order of placeholders for usage from Dart code, you can do that by adding meta info for the key:
In this case you will use given key in your Dart code by passing first name as the first parameter, and then last name as a second parameter:
In order to format a number or date & time, you need to format the value in Dart code and pass the formatted string value to translation string key getter.
Commands
The extension provides several commands for working with Flutter localization.You can access all of the below commands from the Command Palette (
Cmd+Shift+P
or Ctrl+Shift+P
).Flutter Intl: Initialize
Creates the inital binding between translations from .arb files and your Flutter app.The command will create a default locale
en
, the locale that will be used for auto-complete support for keys in Dart code.The following file will be created:
Additionally this command will update
pubspec.yaml
file with plugin config which you can change manually later:Flutter Intl: Add locale
Adds another locale to your Flutter app.The command will ask you for a new locale.
The following file will be created:
Flutter Intl: Remove locale
Removes an existing locale from your Flutter app.The command will ask you to pick a locale from the list of existing locales.
The following file will be removed:

Extract to ARB files
Extract string to ARB files using code actions. The dialog will ask you to enter the string key, which will be extracted to ARB files together with the selected content.
