Not open PaymentSheet

[ambr89]

Describe the bug
When we invoke Stripe.instance.presentPaymentSheet() not appear bottom sheet.

To Reproduce
Steps to reproduce the behavior:

1. invoke Stripe.instance.presentPaymentSheet() after right initialization.

Expected behavior
Open bottom sheet.

Smartphone / tablet

• Device: Iphone 8 Plus
• OS: 16.7.11

• Flutter version 3.29.0

Additional context
When we invoke Stripe.instance.presentPaymentSheet(), we can see these logs.
It seems that it can't show because of a rendering problem.

Did you run initpaymentsheet before presenting what are the settings? Also give me an exact reproduction scenario so I can triage it because presentpaymentsheet works on example app

[ambr89]

Yes before I've run initpaymentsheet
And other information, on the Android system works well.

return Stripe.instance.initPaymentSheet(
          paymentSheetParameters: SetupPaymentSheetParameters(
            applePay: PaymentSheetApplePay(
              merchantCountryCode: 'IT',
            ),
            googlePay: PaymentSheetGooglePay(
                merchantCountryCode: 'IT',
                testEnv: false // true in debug
            ) ,
            style: ThemeMode.light,
            merchantDisplayName: 'MY_MERCHANT_NAME',
            paymentIntentClientSecret: 'MY_SECRET'
          ));

PaymentSheetPaymentOption returned from initPaymentSheet method is null.

Thanks in advance

[remonh87]

did you follow all instructions in the readme? I really cannot reproduce it in our example app using your suggestions. Is there a way you can share me a reproduction app so we can triage the problem?

[AlleCristo]

Hi @remonh87 I work with @ambr89 and wanted to add some more information.

We've encountered this issue specifically on iOS. We've checked the README, and our project is set to platform :ios, '15.6'.

Our main suspicion is that some recent changes made to our AppDelegate might be conflicting with the Flutter Stripe plugin.

Here's the content of AppDelegate.swift

Hope this can help you to reproduce the issue and triage the problem!

import Flutter
import Firebase
import GoogleMaps
import UIKit
import app_links
import FBSDKCoreKit // Per Login Facebook con plugin flutter_facebook_auth

@main
@objc class AppDelegate: FlutterAppDelegate {

        // This will allow us to check if we are coming from a universal link and get the url with its components
        // The activity type (NSUserActivityTypeBrowsingWeb) is used when continuing from a web browsing session to either
        // a web browser or a native app. Only activities of this type can be continued from a web browser to a native app.

        print("AppDelegate DLink Config")

        guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
          let url = userActivity.webpageURL,
          let components = URLComponents(url: url, resolvingAgainstBaseURL: true)
        else {
            return false
        }

        // Now that we have the url and its components, we can use this information to present appropriate content in the app
        return true
    }

        }

        // 2. Load the contents of the plist file into a dictionary
        //    Using NSDictionary is convenient for reading plists directly.
        guard let plistDict = NSDictionary(contentsOfFile: filePath) else {

    }

The changes we made to AppDelegate were necessary because we've migrated from Firebase Dynamic Links to App Links for iOS. This was due to Google's upcoming deprecation of Dynamic Links. As part of this migration, we also added FlutterDeepLinkingEnabled to our Info.plist.

We've also observed a specific issue in the Xcode logs:
Attempt to present <STP_Internal_BottomSheetViewController: 0x114032400> on <UIViewController: 0x112428850> (from <UIViewController: 0x112428850>) whose view is not in the window hierarchy.
We've already checked if the context is mounted, and it never appears to be disposed despite this error.

@AlleCristo thank you for sharing the delegate. I think you commented out

GeneratedPluginRegistrant.register(with: self) and if I am correct we need this for flutter to crrectly register the plugins. Flutter adds this as part of the app delegate when creating an app

[AlleCristo]

Thanks for replying @remonh87 , you're right but i was missing sharing the SceneDelegate.swift...

We had to move the GeneratedPluginRegistrant.register(with: self) to our SeneDelegate in order to handle another plugin we've developed.. but it will be called anyway on each run.

We also tried to delay the call to Stripe.instance.presentPaymentSheet(); after doing the init like this but we had no positive feedback..

initPaymentSheet

Stripe.instance.initPaymentSheet(
          paymentSheetParameters: SetupPaymentSheetParameters(
            applePay: PaymentSheetApplePay(

            ),
            googlePay: PaymentSheetGooglePay(
                merchantCountryCode: 'IT',
                testEnv: false //  testEnv: true, //TODO: Remove this for Prod
            ) ,
            style: ThemeMode.light,
            merchantDisplayName: '***OBSCURED***',
            //customerId: _paymentSheetData!['customer'],

I am highly sceptical this scenedelegate will work. You create a new FlutterEngine which makes things highly complex as you need to make sure that Flutter registers all the plugins correctly. I would try if I were you to start with a simple app delegate like:

import UIKit
import Flutter

@main
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

and slowly adding more complexity. We rely on Flutter's standard way of intialising plugins as we need to initialise Stripe's ios sdk.

Hi @remonh87

All problem is made by this part in our Info.plist file.

Our solution NEEDS it, and we have removed it only for testing.
Do you have any ideas?

	<dict>
		<key>UIApplicationSupportsMultipleScenes</key>
		<false/>
		<key>UISceneConfigurations</key>
		<dict>
			<key>UIWindowSceneSessionRoleApplication</key>
			<array>
				<dict>
					<key>UISceneConfigurationName</key>
					<string>Default Configuration</string>
					<key>UISceneDelegateClassName</key>
					<string>$(PRODUCT_MODULE_NAME).SceneDelegate</string>
					<key>UISceneStoryboardFile</key>
					<string>Main</string>
				</dict>
			</array>
		</dict>
	</dict>

I have no idea to be honest I would recommend making a separate flavor but this is out of scope of our library
