@matanlurey Would you like to review this PR, since you worked on it before? If not I can handle it.

Thanks in advance!

Generally looking good to me except for one.

  int get alpha => _effectiveColor.alpha;

+  @Deprecated(
+    'Use (*.b * 255.0).round() & 0xff. '


Is & 0xff correct? While this operation seems to deal with the cases where (*.b * 255.0).round() is out of [0, 255], it won't because 0xff will convert 256 to 0. I think it should be

Suggested change

'Use (*.b * 255.0).round() & 0xff. '

'Use (*.b * 255.0).round().clamp(0, 255). '

Hi @dkwingsmt, thanks a lot for your review.

I agree that clamping is better than & 0xff. I copied this comment from the Color class:

flutter/engine/src/flutter/lib/ui/painting.dart

Lines 284 to 286 in 8d126a9

/// The blue channel of this color in an 8 bit value.

@Deprecated('Use (*.b * 255.0).round() & 0xff')

int get blue => (0x000000ff & value) >> 0;

Maybe then it makes sense to update the comments in Color class as well as _floatToInt8 method and _fromARGBC constructor? What do you think?

flutter/engine/src/flutter/lib/ui/painting.dart

Lines 217 to 219 in 8d126a9

static int _floatToInt8(double x) {

return (x * 255.0).round() & 0xff;

}

flutter/engine/src/flutter/lib/ui/painting.dart

Lines 176 to 177 in 8d126a9

const Color._fromARGBC(int alpha, int red, int green, int blue, ColorSpace colorSpace)

: this._fromRGBOC(red, green, blue, (alpha & 0xff) / 255, colorSpace);

Hi @gaaclarke, as far as I know, you worked on wide gamut support, so could you please help us here?

Yea that sounds like a fine change if you want to make it. It only matters if you have values outside of [0,1]. We don't force that because for the extended srgb colorspace, that's valid. So, using extended srgb with legacy component accessors could result in unexpected results.

On the other hand, clamping is more expensive than the bitwise-and. This isn't really a big deal because the deprecation of the old accessors happened at the same time as the introduction of extended srgb, so it wasn't breaking anyone.

Maybe then it makes sense to update the comments in Color class as well as _floatToInt8 method and _fromARGBC constructor? What do you think?

I think that's a good change :)

For the record: The following table compares the conversion results of the 3 approaches, which are & 0xff, .clamp, and nothing at all.

(No postprocess) & 0xff .clamp(0, 255)

-0.004 -1 255 0

0.000 0 0 0

0.004 1 1 1

...

0.996 254 254 254

1.000 255 255 255

1.004 256 0 255

Although & 0xff also manages to limit the result within [0, 255], it does so in an discontinuous way and is probably never what users want either.

I am not sure about whether the deprecation notice has to be added on the website, as CupertinoDynamicColor is a Color and such a notice for Color already exists here: https://docs.flutter.dev/release/breaking-changes/wide-gamut-framework

Yeah I think it's worth a short notice, which can largely refers to https://docs.flutter.dev/release/breaking-changes/wide-gamut-framework. Thank you for noticing it!

ksokolovskyi · 2025-07-23T12:42:20Z

@dkwingsmt @gaaclarke Thanks for your reviews!

I've replaced & 0xff with .clamp(0, 255) where it was possible. Unfortunately, it is not possible to use the clamp method in Color._fromARGBC and Color._fromRGBOC as those constructors are const, so I left & 0xff there in place.

As well, I've filed a website PR which adds a breaking change doc explaining introduced deprecations: flutter/website#12236

#12236) Adds breaking changes doc for deprecations introduced in `CupertinoDynamicColor` after wide gamut changes.

Apologies for the mix up while I remembered why those others we omitted. I was able to fix the newline, so I think we can go ahead an land this!
