after adding packages in project, android is ok but ios crash during start in flutter

I'm adding packages to my application.

flutter:
  sdk: flutter
http: ^0.12.0
shared_preferences: ^0.5.2

Successfully ran on Android device. Then I was this command to build for iOS:

flutter build ios

And successful building and installing in xcode. But when running the app in a device I get this error:

#import <Flutter/Flutter.h>

#import "AppDelegate.h"

int main(int argc, char * argv[]) {

@autoreleasepool {

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));  **Thread 1: signal SIGABRT**

  }

}

Thread 1: signal SIGABRT

How can I fix it??

Solution 1: Sharad Paghadal

do flutter clean and

go to ios folder by cd ios

then install pods by pod install

then try building ios module by flutter build ios --release.
