描述

bug deferred (post-5.0)
Before submitting a new issue
  • I tested using the latest version of the library, as the bug might be already fixed.
  • I tested using a supported version of react native.
  • I checked for possible duplicate issues, with possible answers.
Bug summary

When defined in TailwindCSS's @theme directive, if a variable depends on another's value, (for example, --color-primary: hsl(var(--primary))), updating the source variable (--primary in this example) in VariableContextProvider doesn't propagate to the derived variable (--color-primary in this example).

Steps to reproduce
  1. In your global.css add:
@theme {
	--color-primary: hsl(var(--primary));
}
@layer base {
	:root {
    	--primary: 0 0% 9%;
     }
}
  1. Then anywhere in your React Native tree:
<VariableContextProvider
	value={{
		'--primary': '80 76% 61%', // green
	}}
>
	{/* Doesn't work, renders the static `--primary` defined in global.css (`hsl(0 0% 9%)`) */}
	<View className="size-10 bg-[var(--color-primary)]" />
	{/* Renders green - variable is working */}
	<View className="size-10 bg-[hsl(var(--primary))]" />
</VariableContextProvider>

I've tried reproducing without any values in .css, but the following won't work. That seems to be a different bug?

<VariableContextProvider
	value={{
		'--custom': '0 0% 9%',
		'--custom-color': 'hsl(var(--custom))',
	}}
>
	<VariableContextProvider
		value={{
			'--custom': '80 76% 61%',
		}}
	>
		{/* Doesn't work - apparently var(--color-custom) never got defined with a valid --custom value */}
		<View className="size-10 bg-[var(--color-custom)]" />
		{/* Works */}
		<View className="size-10 bg-[hsl(var(--custom))]" />
	</VariableContextProvider>
</VariableContextProvider>

Thank you for your work in this amazing library! Huge unlock being able to port a good chunk of my web skills into RN UI 😄
