IOS 13.3 TextStyle FontWeight being completely Ignored

Hi, after upgrade my ios to 13.3, my flutter app cannot display bold (compare to before upgrade and in android)

Is it problem with ios 13.3 ? Or there's breaking changes in flutter for ios ? Android works fine

@x4080

Hi @x4080
can you please provide your flutter doctor -v ,
and if possible a reproducible minimal code sample.
Thank you

Attached the result in ios simulator and android emulator using bold

Bold is not displaying in IOS

(edited)

Confirm. Flutter 1.14.5. iOS 13.3. Font with bold weight (and w500, w600, w700 .....) is not displayed for the emulator and on the real device.

@pamir72

@pamir72 thanks so its not just me

It's not only headline5. Any with bold for me

This should be fixed on master now, after #51480

Can anyone experiencing this pleast test on master and verify?

I can verify the fix is working.

Side note: Upgrading from beta to master wasn't easy due to some recent breaking changes I ran into #48346, #44930, #51435

Verified too, on master commit 1cc8cc299

I confirm, fixed.

@dnfield

@dnfield will this be expedited to the beta channel, or are the dependencies too big to allow it?

@tvolkert

@tvolkert

@scopendo

@scopendo it should make it to the beta channel in the next beta release, but it won't be cherry-picked, so the next beta release will also contain the API-breaking changes you see on master.

@tvolkert

Hey @tvolkert. I'm new to flutter dev so sorry if this is an obvious question. But are there periodic releases to beta channel or is it just "whenever it happens"? Just trying to figure out if I can wait for this or find an alternative. Thank you!

@jlubeck

@jlubeck see https://github.com/flutter/flutter/wiki/Release-process#rolling-the-beta-channel. tldr: beta releases are generally once a month early in the month (will likely be early next week).

Side-note: we're in the process of defining a new release process that should allow us to publish a calendar so people can plan on our beta and stable releases. Stay tuned 🙂

@tvolkert

Nice, thank you @tvolkert !

Nice, beta was published and this is now fixed on beta channel
