Setting up Badges for Flutter

This guide describes the process of implementing Badges for Pushwoosh Flutter plugin

1. Open your iOS project located in your_project/ios/Runner.xcworkspace and create NotificationServiceExtension:

2. Open Podfile (located in your_project/ios/Podfile) and add PushwooshXCFramework dependency fo NotificationServiceExtensionTarget:

target ‘NotificationService’ do
  pod ‘PushwooshXCFramework’, ‘>=6.5.0’
end

You can put these lines after target ‘Runner’ do like in the example below:

Podfile example

target ‘Runner’ do
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
target ‘NotificationService’ do
  pod ‘PushwooshXCFramework’, ‘>=6.5.0’
end
post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

3. Install pods via Terminal:

cd ios && pod install

4. Close and reopen your Xcode project.

Make sure that you open the project via .xcworkspace and not via .xcproject.

5. Make sure that your Deployment target matches the one in the Runner target; otherwise, you might face an issue when building your app (e.g., if you specify iOS 10.0 in Runner and iOS 15.5 in NotificationService targets).

6. Add App Groups capability to both Runner and NotificationService targets and add a new group with the same name for both targets:

7. Add PW_APP_GROUPS_NAME info.plist flag to both Runner and NotificationService targets with the group name as its string value:

8. Go to NotificationService.m and replace its code with the following:

#import “NotificationService.h”
#import <Pushwoosh/PWNotificationExtensionManager.h>

@interface NotificationService ()
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@end

@implementation NotificationService
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    [[PWNotificationExtensionManager sharedManager] handleNotificationRequest:request contentHandler:contentHandler];
}
- (void)serviceExtensionTimeWillExpire {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your “best attempt” at modified content, otherwise the original push payload will be used.
    self.contentHandler(self.bestAttemptContent);
}
@end

That's it!
