'FirebaseMessaging/FirebaseMessaging.h' file not found

[tuanha2000vn]

Hi guys, I've spend days but can't fix that strange bug. The code work fine last month but now can't build.

Bug:

#import <FirebaseMessaging/FirebaseMessaging.h> => 'FirebaseMessaging/FirebaseMessaging.h' file not found

Any help would be greatly appreciated. Thank you.

What I have done:

Clear, clean, reinstall with the following command:

% flutter clean
% rm -rf "${HOME}/Library/Caches/CocoaPods"
% rm -rf "`pwd`/Pods/"
% pod install

This is the file where error occur:

#import "NotificationService.h"
#import <FirebaseMessaging/FirebaseMessaging.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];
    
    // Modify the notification content here...
    //self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.title];
    
    //self.contentHandler(self.bestAttemptContent);
    // Call FIRMessaging extension helper API.
    [[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent withContentHandler: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

This is flutter doctor -v
