HOW TO MAKE A FLUTTER APP PART-1
First of all, we have to select an Operating System for installation purpose. We have three options: Windows, macOS and Linux.
Lets say we have started the installation for Windows Operating System. Now there are some minimum system requirements to install and run Flutter App.
- Operating System: Windows 7 SP1 or later (64 bit)
- Disk Space: 400 MB
- Tools: Flutter depends on the following:
- Windows PowerShell 5.0 r newer
- Git for Windows 2.x
- Download the installation from the following link: https://storage.googleapis.com/flutter_infra/releases/stable/windows/flutter_windows_v1.12.13+hotfix.5-stable.zip
- Extract the zip File and place the contained FLUTTER folder i the desired location.
Run the following Command.
$ git clone https://github.com/flutter/flutter.git
Update your path
If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the PATH environment variable:
- From the Start search bar, enter ‘env’ and select Edit environment variables for your account.
- Under User variables check if there is an entry called Path:
- If the entry exists, append the full path to flutter\bin using ; as a separator from existing values.
- If the entry doesn’t exist, create a new user variable named Path with the full path to flutter\bin as its value.
Run flutter doctor
- From a console window that 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:
- This command checks your environment and displays a report of the status of your Flutter installation. Check the output carefully for other software you might need to install or further tasks to perform (shown in bold text).
Install Android Studio
- Download and install Android Studio (https://developer.android.com/studio)
- Start Android Studio, and go through the ‘Android Studio Setup Wizard’.
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 4.1 (API level 16) 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 devicescommand to verify that Flutter recognizes your connected Android device. By default, Flutter uses the version of the Android SDK where your
adbtool is based. If you want Flutter to use a different installation of the Android SDK, you must set the
ANDROID_HOMEenvironment variable to that installation directory.
Set up the Android emulator
To prepare to run and test your Flutter app on the Android emulator, follow these steps:
- Enable VM acceleration on your machine.
- Launch Android Studio > Tools > Android > AVD Manager and select Create Virtual Device. (The Android submenu is only present when inside an Android project.)
- Choose a device definition and select Next.
- Select one or more system images for the Android versions you want to emulate, and select Next. An x86 or x86_64 image is recommended.
- Under Emulated Performance, select Hardware – GLES 2.0 to enable hardware acceleration.
- Verify the AVD configuration is correct, and select Finish.
For details on the above steps, see Managing AVDs.
- In Android Virtual Device Manager, click Run in the toolbar. The emulator starts up and displays the default canvas for your selected OS version and device.
Warning: Flutter on the web is currently available as a technical preview. When trying Flutter apps on the web, you can expect to experience crashes and missing features. If this happens, please file an issue.
To prepare to run and test your Flutter app on the web, you must install Chrome, if you haven’t already.
