Changing the config dynamically doesn't apply the new config

[endrits079]

Description

If the config is changing it is not reflecting on the components.

Steps to reproduce

1. Create 2 configs.

2. Have a state to decide which config to use

3. Based on the state provide a config object:
   function ThemedApp({children}: {children: React.ReactNode}): JSX.Element {
   const [config, setConfig] = useState("blue")
   const themeConfig = useMemo(
   () => config === "blue" ? blueConfig : greenConfig ,
   [config],
   );
   return (
   
   {children}
   
   );
   }

4. Have a button that changes the state (for example between green and blue ) if the green config has primary color as green and blue config primary color as blue then it is not applying it is stuck on initial ( which is blue in this case )

Additional Information

A simple code example:

import {Button} from "@gluestack-ui/themed"
import {blueConfig, greenConfig} from "./config"

function ThemedApp({children}: {children: React.ReactNode}): JSX.Element {
  const [config, setConfig] = useState("blue")
  const themeConfig = useMemo(
    () => config === "blue" ? blueConfig : greenConfig ,
    [config],
  );
  return (
    <GluestackUIProvider config={themeConfig} colorMode="light">
      {children}
     <Button onPress={()=>{
        setConfig(prev=>prev==="blue" ? "green" : "blue")
     }}>Change config</Button>
    </GluestackUIProvider>
  );
}

Hey @endrits079, Thanks for reporting the issue. We'll look into it.

Same here. Not sure if it's related but changing descendent color takes effect only after a reload.
Is there some sort of caching ? Removing a style prop sometimes doesn't takes effect.

Same here.
I use different config to fit different theme colors.
When colorMode changes, the view is not updated:

// Be executed somewhere
export let setColorMode: React.Dispatch<React.SetStateAction<COLORMODES>>;

export const ThemeProvider = (props: PropsType): React.JSX.Element => {
  const [colorMode, _setColorMode] = useState<COLORMODES>('dark');
  setColorMode = _setColorMode;

  // use dynamic colorMode returns different color configurations  
  const config = useMemo(() => createUIConfig({ colorMode }), [colorMode]);

  return (
    <GluestackUIProvider
      colorMode={colorMode}
      config={{
        ...config,
        components: componentsConfig,
      }}>
      {props.children}
    </GluestackUIProvider>
  );
};

I can't find the answer in the source code, can someone tell me if this is fixable? @ankit-tailor

Similar issue here. I'm ejecting and then making updates to the theme components (as described here https://gluestack.io/ui/docs/theme-configuration/customizing-theme) in the generated config folder, but changes aren't taking effect until I do a reload.

@ankit-tailor any updates on this issue?

Hey @endrits079, after some discussion we concluded that supporting this feature would take some toll on the performance which we are not in favor of right now. Hence we have decided to pause this, until we find a solution to effectively add this feature without any performance overhead.
