Smartphone (please complete the following information):

• Device: iphone 8(simulator), iphone 12 max (simulator), iphone 7 pro (real device)
• OS: iOS 14.5
• Browser: stock
• Version: Safari 14.1

Additional context This is just an observation, in the screenshot provided above, the if statement, checks if the Map options is null OR path is null, but proceeds to traverse over the keys' even tho the map is null. so i think there should be an inner check skipping the map iteration if the map is null.

update:

so i thought perhaps i can pass the options parameter when i call List function. now my function call looks like this: var res = await Amplify.Storage.list(path: path,options: ListOptions(accessLevel: StorageAccessLevel.guest));

And it resolved the above crash! but now am faced with an Exception instead!, a Format Exception to be precise.

`[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: FormatException: Invalid date format ٢٠٢١-١٠-٢٨ ١٤:٣٣:٥٥ +0000

0 DateTime.parse (dart:core/date_time.dart:330:7)

1 AmplifyStorageS3MethodChannel._formatListResult (package:amplify_storage_s3/method_channel_storage_s3.dart:215:28)

2 AmplifyStorageS3MethodChannel.list (package:amplify_storage_s3/method_channel_storage_s3.dart:141:27)

`

the Amplify Storage API seems to use the Device's Locale to receive data in the Locale's language code. in this case, my device was in Arabic. and the returned property Last Modified of my list object is now in Arabic numerals which caused a format exception. is there a possibility of ignoring the app/device's locale? and just default to English, i can format the data returned if i need to.

Greetings, when could we see the fixes for this issue deployed to the flutter plugin? we're currently delaying our iOS app production deployment till these fixes are push to the plugin.

Hi @Ozak93 - thank you for your patience resolving this issue. Version 0.2.8 has been released with the fix and I'd be excited to know how it works for you. Please let me know if you experience this or any other issues, and I hope have a great weekend!

[Ozak93]

Thank you so much, the issue seems resolved!
