@jmagman shouldn't #60145 be added to that list?

[jmagman]

Added, thanks @EliasDeuss.

Also #60034

I'm moving the font issue up. It's too noticeable.

I'm moving the font issue up. It's too noticeable.

Yea and the iOS 14 Public beta is rolling out today so it will probably be affecting more people now.

Added pencil scribble to non blocking list

Anybody with a solution for the crash problem?
almost 3 weeks of me unable to run my apps on my device :(

[timsneath]

Sorry for the inconvenience. To be clear, we don't guarantee to support early beta versions of pre-release software. As per the Apple beta documentation:

Please note that since the public beta software has not yet been commercially released by Apple, it may contain errors or inaccuracies and may not function as well as commercially released software. Install the beta software only on non-production devices that are not business critical. We strongly recommend installing on a secondary system or device, or on a secondary partition on your Mac.

The reason for beta releases like this is to allow time for developers to update to the latest version, which is what we're doing. We're working on these issues ahead of the official release, but if you need to run your app on that device now, you'll need to downgrade.

Thanks for supporting Flutter!

I moved #60145 out of blocker since it won't trigger a system notification on master. The remaining bug is just to re-enable clipboard detection before showing the paste button.

Related to fonts on iOS 14 #64528

[xster]

#64528 is a duplicate. We're ok there.

[edeuss]

Looks like iOS 14 and iPadOS 14 will roll out tomorrow.

[timsneath]

Thanks @EliasDeuss. We've been preparing for this for a while, and now that we have a clear timeframe, we know what we need to spin up ahead of the iOS 14 rollout. Stay tuned for more in the next 24 hours.

[jmagman]

We didn't have a proper standalone issue for prompting the "would like to find and connect to devices on your local network" popup when the dart observatory publishes, so added #65138 PR to the blocked list (already merged). More investigation information in #63893.

Moved #63893 out of blockers since it's now tracking an add-to-app documentation issue.

Just posted, here:
https://medium.com/flutter/supporting-ios-14-and-xcode-12-with-flutter-15fe0062e98b

TL;DR Flutter 1.22 (just released to beta channel) includes preliminary support for iOS 14 and Xcode 12. Please let us know if you experience any issues that aren't tracked above.

[jmagman]

@Jeremywhiteley @aseef17 Let's have discussions about bugs and features in their respective issues (#60026). This is an umbrella issue tracking all of it.

[yanweimin7]

when did 1.17.x support ios14, any progress ?

[vasilich6107]

@yanweimin7 I assume that 1.17.x will never support ios14
You need to upgrade to 1.20.x or latest beta

[jmagman]

The Medium article linked above explains that, other than the clipboard notification problem, your existing deployed apps should continue to work on your customers' iOS 14 devices. However, for you the developer to use iOS 14 for debugging, etc. you will need to upgrade to the Flutter 1.22 beta. You can look at the list in this issue to see what features and bug fixes you'll be missing out on if you don't upgrade.

If your iOS 14 app uses TextField, CupertinoTextField, or TextFormField, you’ll want to make sure that it’s built with Flutter 1.20 or later to ensure that your users are not bothered by unnecessary clipboard notification messages, as per Apple’s updated clipboard policy.
Otherwise, existing production apps will run just fine on your end-users’ iOS 14 devices. However, if you’re upgrading your development phone to iOS 14 today and want to continue to use it with Flutter, you have two choices.
Your first choice is to use the latest hotfix release of Flutter on the stable channel (1.20.4), which supports development-time deployment to physical iOS 14 devices. Unfortunately, there’s another change that is quite a bit more intrusive (and therefore more risky) which is needed for debugging and hot reload on iOS 14. We’re deferring this fix to our next stable release, which we are planning to release in the next few weeks.

Flutter's policy is to not hotfix older stable versions:
https://github.com/flutter/flutter/wiki/Hotfixes-to-the-Stable-Channel

Note that we only hotfix the latest version --- if you see bugs on older versions of the stable channel, please consider moving to the latest stable channel version.

Let's track the remaining iOS 14 features individually now that it's been out awhile. Closing this umbrella issue.
