Upcoming Cupertino Library Features #43041
Description
This is a list of the new Cupertino library features that we're likely to work on in the next three months. It does not include the ongoing work related to bugs and other existing issues. The goal is to emphasize new widgets and features we're hoping to work on in near term, and to solicit feedback. We'd welcome comments about the features listed here and features we may have missed.
Features for which the work is relatively complete are marked with ✔️.
This issue obsoletes #35026, which covered July-September 2019. The comments and votes submitted for #35026 will not be forgotten, it's assumed that they all still apply to this new roll up.
There's a similar list of Material library features, see #43035.

Simplified I18N Process
Apps will use a tool to generate a localized resources class from handwritten application resource bundle (".arb") files, one per supported locale.

Systematic Fidelity Measurement and Tracking
Measure look and feel fidelity by comparing Flutter with native apps. This process needs to be part of post-submit testing; just like performance benchmarking.
The goal is to verify that a user can not distinguish between native and Flutter apps for visuals and behaviors that are intended to match their native counterparts.
This project applies to both the Cupertino and Material libraries.
Autofill Support ✔️
The overall goal for this project will be to add engine support for the native autofill services, provide an SDK widget that exposes the autofill service data, and integrate autofill with the default text selection menu.
This is also part of the upcoming Material features.
