SDK Installation

1. Download the Flutter SDK here.

2. Unzip the downloaded SDK zip file to a folder in your local drive.

3. Setup the SDK:

   cd vital_sign_camera
   flutter pub get

Sample Code

The quickest and simplest way to kickstart your journey with the Flutter SDK is by downloading and experimenting with our full-featured sample code. To run the sample code, go to the demo_app folder, execute the commands:

flutter pub get
flutter run

IMPORTANT

In the above sample codes, the strings __YOUR_USER_ID__ and __YOUR_API_KEY__ should be replaced by your own User ID and API Key repectively. Please contact us to obtain your User ID and API Key.

Project Integration

To integrate our Flutter SDK into your Flutter project, add the Flutter SDK package by:

flutter pub add vital_sign_camera --path "/path_of_downloaded_folder/flutter-vital-sign-sdk/vital_sign_camera"

Please replace the string path_of_downloaded_folder above with the actual downloaded path.

Project Integration (for iOS)

IMPORTANT

Please note that for iOS, the SDK requires targeting iOS 12 or above.

Add the following to the 'ios/Podfile' file for the iOS simulator support:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # Support x86_64 simulator only
      config.build_settings['ARCHS[sdk=iphonesimulator*]'] = 'x86_64'
    end
    flutter_additional_ios_build_settings(target)
  end
end

Also in the 'ios/Podfile' file, update the line use_frameworks! to:

use_frameworks! :linkage => :static

Camera Permission

When developing for iOS, you need to allow the app to use the camera by specifying the following in the file Info.plist:

<key>NSCameraUsageDescription</key>
<string>Use for measuring vital signs</string>

TIP

In Info.plist, the string "Use for measuring vital signs" is an example description of the camera usage. You should specify your own description that matches the usage of your application.

Project Integration (for Android)

IMPORTANT

Please note that for Android, the minimum SDK version must be at least 24.

Add the following line to the file android/settings.gradle:

include ':vital-sign-engine'
project(':vital-sign-engine').projectDir = new File('/path_of_downloaded_folder/flutter-vital-sign-sdk/vital_sign_camera/android/libs')

Please replace the string path_of_downloaded_folder above with the actual downloaded path.

Camera Permission

When developing for Android, you need to allow the app to use the camera by specifying the following in the file AndroidManifest.xml:

<uses-permission android:name="android.permission.CAMERA" />
