[Impeller] Impeller and Skia gradients disagree on behavior for invalid color stops (outside of the range of 0.0 to 1.0) #132792
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
- Run the sample code in IOS build
a. With Impeller Enabled (can just use latest default Flutter project)
b. Without Impeller Enabled (can use Flutter < v3.10, or disable in info.plist with the following code:
<key>FLTEnableImpeller</key>
<false />
Expected results
Linear gradient is rendered consistently as before.
Actual results
Linear gradient is rendered as a flat color.

I am using a specific flutter version via checking out the tag in my Flutter SDK git repo, hence the warning about not being on a channel. But this error persists regardless of that.[!] Flutter (Channel [user-branch], 3.13.0, on macOS 13.5 22G74 darwin-x64, locale en-US)
! Flutter version 3.13.0 on channel [user-branch] at /Users/liam.hockley/fvm/versions/3.7.12
Currently on an unknown channel. Run `flutter channel` to switch to an official channel.
If that doesn't fix the issue, reinstall Flutter by following instructions at
https://flutter.dev/docs/get-started/install.
! Upstream repository unknown source is not a standard remote.
Set environment variable "FLUTTER_GIT_URL" to unknown source to dismiss this error.
