<!-- TODO Return Ad controlled by the android:value below -->
    android:value="false" />

Splash Ads are enabled by default. If you want to disable them, add <provider> tag into AndroidManifest.xml file with another <meta-data> tag nested in that provider as shown below.

<!-- TODO Splash Ad controlled by the android:value below -->
        android:value="false" />

<!-- TODO replace YOUR_APP_ID with actual value -->

  • The Start.IO SDK doesn't contain arm64 slice for iOS simulator. Therefore, if needed,  you would be required to modify the relevant settings following the instructions below


In order to build your app for iOS simulator on Apple silicon computer the Excluded Architecturesbuild setting for iOS simulator should contain arm64. Flutter generates xcconfig file Generated.xcconfig with EXCLUDED_ARCHS[sdk=iphonesimulator*]=i386  and ignores those settings, specified in podspec file. 

Needed Modification settings for arm64 slice for iOS simulator:

  1. Open the default Xcode workspace in your project by running open ios/Runner.xcworkspace in a terminal window from your Flutter project directory.
  2. Select Runner project in Project navigator
  3. Select Runner Target
  4. Click on Build Settings tab
  5. Find Exluded Architectures
  6. Add arm64 for Any iOS Simulator SDK


Initializing the Plugin

Get an instance of StartAppSdk by calling its default constructor. It is safe to call this constructor multiple times - you'll get the same singleton instance.

class _MyAppState extends State < MyApp >  {
    var startAppSdk = StartAppSdk();
