How To Run Flutter App On Android Phone

Introduction

Flutter is Google's mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used past developers and organizations around the world, and is complimentary and open up source.

What does Palpitate do? Can you lot build iOS apps using Flutter?

For users, Flutter makes cute app UIs come to life. For developers, Flutter lowers the bar to entry for building mobile apps. It speeds upwardly the development of mobile apps and reduces the cost and complexity of app production across iOS and Android. For designers, Flutter helps evangelize the original design vision, without loss of fidelity or compromises. It as well acts equally a productive prototyping tool.

Install

Arrangement requirements

To install and run Flutter, your development environment must see these minimum requirements:

Operating Systems: macOS (64-chip)
Deejay Space: 700 MB (does not include disk infinite for IDE/tools).
Tools: Palpitate depends on these control-line tools beingness bachelor in your environs.
fustigate, mkdir, rm, git, ringlet, unzip, which

Get the Flutter SDK

Clone blastoff branch from Flutter repository using Git and add bin folder to your PATH.

$ git clone https://github.com/flutter/flutter.git -b blastoff
$ export PATH=`pwd`/flutter/bin:$PATH

The above command sets your PATH variable temporarily, for the current final window. You are now gear up to run Flutter commands!

Note: To permanently add Flutter to your path, see the reference https://flutter.io/setup-macos/#update-your-path.

Run flutter doctor

Run the post-obit control to see if at that place are any dependencies you need to install to complete the setup:

$ flutter doctor

This command checks your environs and displays a study to the concluding window. The Sprint SDK is bundled with Flutter; it is non necessary to install Dart separately.

For example:

Platform setup

macOS supports developing Flutter apps for both iOS and Android. Consummate at least one of the two platform setup steps now, to be able to build and run your first Palpitate app.

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 sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer from the control line.This is the correct path for most cases, when you desire to use the latest version of Xcode. If you need to utilize a different version, specify that path instead.

Make sure the Xcode license agreement is signed by either opening Xcode in one case and confirming or running sudo xcodebuild -license from the control line.

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

Deploy to iOS devices

To deploy your Palpitate app to a physical iOS device, yous'll need some boosted tools and an Apple account. You'll also need to set up physical device deployment in Xcode.

Install homebrew.
Open up the terminal and run these commands to install the tools for deploying Palpitate apps to iOS devices.

$ brew update
$ brew install --HEAD libimobiledevice
$ mash install ideviceinstaller ios-deploy cocoapods
$ pod setup

If any of these commands fails with an error, run brew doctor and follow the instructions for resolving the upshot.

Follow the Xcode signing menstruum to provision your project:
Open the default Xcode workspace in your project by running open ios/Runner.xcworkspace in a last window from your Flutter projection directory.
In Xcode, select the Runner project in the left navigation panel.
In the Runner target settings folio, brand sure your Development Team is selected netherGeneral > Signing > Team. When you select a team, Xcode creates and downloads a Development Certificate, registers your device with your account, and creates and downloads a provisioning profile (if needed).
To start your first iOS evolution project, you may need to sign into Xcode with your Apple tree ID.

Evolution and testing is supported for any Apple tree ID. Enrolling in the Apple Developer Program is required to distribute your app to the App Store. View the differences betwixt Apple membership types.
The showtime time you lot employ an fastened physical device for iOS development, y'all volition need to trust both your Mac and the Evolution Document on that device. Select Trust in the dialog prompt when commencement connecting the iOS device to your Mac.

Then, become to the Settings app on the iOS device, selectGeneral > Device Directionand trust your Certificate.
If automatic signing fails in Xcode, verify that the project'southGeneral > Identity > Bundle Identifier value is unique.

Start your app by running flutter run.

How to setup and test Flutter app on Android?

Note:Palpitate relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Palpitate apps in a number of editors; a later footstep will hash out that.

Install Android Studio

Download and install Android Studio.
Start Android Studio, and go through the 'Android Studio Setup Magician'. This volition install the latest Android SDK, Android SDK Platform-Tools, and Android SDK Build-Tools, which are required by Flutter when developing for Android.

Set up and deploy Flutter apps on your Android device

To prepare to run and test your Flutter app on an Android device, y'all'll need an Android device running Android 4.one (API level 16) or higher.

EnableDeveloper options andUSB debugging on your device. Detailed instructions are available in the Android documentation.
Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your figurer to admission your device.
In the terminal, run the flutter devices command to verify that Flutter recognizes your continued Android device.

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

Create Project

Here I created a sample flutter_app project using following terminal command:

flutter create flutter_app
cd flutter_app

Run the app

To list out all connected devices, please use the commandflutter devices to show all:

SM G950U1 • 9887fc41594630315a • android-arm • Android 7.0 (API 24)
iPhone 7 • a0c2865be4ccfe53aea7c280dded0837873104ae • ios • iOS x.three.3

If you have only one device is continued, only use the command flutter run to install your app into the device.

Otherwise, if have more than one device connected; delight specify a device with the '-d <deviceId>' flag, or apply '-d all' to act on all devices.

flutter run -d9887fc41594630315a
palpitate run -d a0c2865be4ccfe53aea7c280dded0837873104ae

Note: For iOS device, if you see the error equally below, please double check the iOS Setup step to fix it.
