Took a few months of research, iteration, and follow-ups to get this right, but it’s worth it to raise the security baseline for Flutter apps.

This update addresses a key security gap on jailbroken iOS devices. By leveraging the Secure Enclave, encryption keys are now hardware-protected and can’t be extracted in plaintext, even on compromised devices.

It’s official: my Secure Enclave support PR is now merged into #flutter_secure_storage 🚀

I just realized you can use null-aware elements in Dart maps too — not just iterables.
It doesn’t look like it at first, but the key is completely omitted when the value is null. #Flutter #Dart #FlutterDev

Nice surprise seeing my contribution pop up in the new @FlutterDev release article 👀

@CFDevelop There’s an open issue that covers this use case, you’ll probably find the reasoning there: github.com/juliansteenbak…
Let me know if it doesn’t answer your question.

@ahmeddhus Why exactly is that necessary? I would have thought that you’d use that from a higher level of abstraction. Why would you actually need to create a key and sign things with the Secure Enclave? What’s the use case?

Remember the Secure Enclave and #Flutter security post?
I’ve submitted a Pull Request to 𝙛𝙡𝙪𝙩𝙩𝙚𝙧_𝙨𝙚𝙘𝙪𝙧𝙚_𝙨𝙩𝙤𝙧𝙖𝙜𝙚 adding Secure Enclave support for iOS:

Still not merged yet, but it’s in progress.
Let’s see where this leads us.

Did you know that?
I'm pretty sure maaaanyyyy @FlutterDev apps do not implement the original design correctly because of that!

I also reported it here and shared a working solution

I came across a UI shifting bug on #iOS 26.0 when using #Flutter plugins that rely on 𝗦𝗰𝗿𝗲𝗲𝗻𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗼𝗿𝗞𝗶𝘁 (like no_screenshot).
The issue happens when Arabic language is enabled, the app UI shifts to the right unexpectedly.

@ulusoyapps @Firebase I faced the same issue before when I restricted my API keys from the Cloud Console. I didn’t really understand why, so I just removed the restrictions since it was only a side project in my case

Hey @Firebase team! Suddenly, I am seeing this error for my Firebase AI logic requests in production. What is happening? 🤔🤨

Ever noticed that if you open #YouTube on your laptop and your TV with the same account, you get different ads?

The right solution is to use the Secure Enclave for key wrapping and only store the wrapped blob in the keychain.
There’s already an open issue about this: github.com/juliansteenbak…
