my build target is 8.0
when I run flutter build iOS,I ran into the error, can someone help? thanks!!

system info: macOS catalina v10.15.2

my pod file:

# Uncomment this line to define a global platform for your project

  'Profile' => :release,
  'Release' => :release,
}

def parse_KV_file(file, separator='=')
  file_abs_path = File.expand_path(file)
  if !File.exists? file_abs_path
    return [];
  end
  generated_key_values = {}
  skip_line_start_symbols = ["#", "/"]
  File.foreach(file_abs_path) do |line|
    next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
    plugin = line.split(pattern=separator)
    if plugin.length == 2
      podname = plugin[0].strip()
      path = plugin[1].strip()
      podpath = File.expand_path("#{path}", file_abs_path)
      generated_key_values[podname] = podpath
    else
      puts "Invalid plugin specification: #{line}"
    end
  end

  • How did you resolve the "fluttertoast" errors? That wasn't addressed in the solution. Commented Apr 9, 2020 at 20:11
  • In my case, there were warnings made by fluttertoast, the warning would not break the build process, you may check about the message to check about if it is real error or warning Commented Apr 19, 2020 at 6:25

As error message says:

/Users/Geek/work/flutter/.pub-cache/hosted/pub.dartlang.org/permission_handler-4.1.0/ios/Classes/strategies/NotificationPermissionStrategy.m:71:5: warning: 'UIRemoteNotificationType' is deprecated:
    first deprecated in iOS 8.0 - Use UserNotifications Framework's UNAuthorizationOptions for user notifications and registerForRemoteNotifications for receiving remote notifications instead.
    [-Wdeprecated-declarations]

You have to add:

if application.respondsToSelector("isRegisteredForRemoteNotifications")
{
    // iOS 8 Notifications
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: (.Badge | .Sound | .Alert), categories: nil));
    application.registerForRemoteNotifications()
}
else
{
    // iOS < 8 Notifications
    application.registerForRemoteNotificationTypes(.Badge | .Sound | .Alert)
}

There is a added issue for this, here.
