Flutter) When accessing an album on iOS, the permission request does not appear

I am using the permission_handler package. The version is 9.0.1.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFNITIONS'] ||=[
        '$(inherited)',
        'PERMISSION_CAMERA=1',
        'PERMISSION_PHOTOS=1' 
      ]
    end
  end
end

My Podfile is the same as above.

    <key>NSCameraUsageDescription</key>
    <string>blahblahblah!</string>
    <key>NSPhotoLibraryUsageDescription</key>
    <string>blahblahblah!</string>

I also put values ​​in NSCameraUsageDescription and NSPhotoLibraryUsageDescription in info.plist.

var photoPermission = await Permission.photos.status;
if (!photoPermission.isGranted) {
    await Permission.photos.request();
}

When debugging while setting a breakpoint, I can see the program entering the await Permission.photos.request(); code. However, the permission request window does not appear.

I also looked for the package's GitHub issue page, but couldn't solve it.
Please help me.

Seems like the third library Compiling wield, It works fine by editing the iOS plugin part source code a little

seen from the source code:

111

in file PhotoPermissionStrategy.h


#import <Foundation/Foundation.h>
#import "PermissionStrategy.h"

#if PERMISSION_PHOTOS

#import <Photos/Photos.h>

@interface PhotoPermissionStrategy : NSObject <PermissionStrategy>
-(instancetype)initWithAccessAddOnly:(BOOL) addOnly;
@end

#else

#import "UnknownPermissionStrategy.h"
@interface PhotoPermissionStrategy : UnknownPermissionStrategy
@end

#endif

turn the above into

#import <Foundation/Foundation.h>
#import "PermissionStrategy.h"

#if 1

#import <Photos/Photos.h>

...

And in file PhotoPermissionStrategy.m

turn

#import "PhotoPermissionStrategy.h"

#if PERMISSION_PHOTOS

@implementation PhotoPermissionStrategy{
    bool addOnlyAccessLevel;
}

...

to

#import "PhotoPermissionStrategy.h"

#if 1

@implementation PhotoPermissionStrategy{
    bool addOnlyAccessLevel;
}

...

easy to debug by logging the source code
