Troubleshooting:
  1. Ensure only one react copy: node_modules/react (no nested copy under library).
  2. Clear Metro cache: npx react-native start --reset-cache.
  3. Verify metro.config.js extraNodeModules maps react to example app node_modules.`)}pe();function K(e){let[n,t]=V(()=>e.get());return z(()=>(t(e.get()),e.subscribe(()=>t(e.get()))),[e]),n}function ye(e){let[n]=V(()=>{let r=typeof e=="function"?e():e;return C(r)});return[K(n),n.set.bind(n)]}import{useEffect as be,useRef as M}from"react";var y=new WeakMap;function me(e,n=[]){let t=M({}),r=M(null),i=M(null);be(()=>{let s=()=>{if(!y.get(t.current)){y.set(t.current,!0);try{r.current&&(r.current(),r.current=null);let o=e();typeof o=="function"&&(r.current=o)}finally{y.set(t.current,!1)}}};return i.current=E(s),()=>{r.current&&r.current(),i.current&&i.current(),y.delete(t.current)}},n)}import Se from"react";import{jsx as he}from"react/jsx-runtime";function Q(e){let n={};for(let t of Object.keys(e))n[t]=e[t].get();return n}function ve(e){return e.displayName||e.name||"Component"}function Z(e,n,t){var r;return r=class extends Se.Component{constructor(o){super(o);this.unsubscribers=[];this.state=Q(n)}componentDidMount(){this.unsubscribeAll(),this.setState(Q(n)),this.unsubscribers=Object.keys(n).map(o=>n[o].subscribe(()=>{this.setState({[o]:n[o].get()})}))}componentWillUnmount(){this.unsubscribeAll()}unsubscribeAll(){for(let o of this.unsubscribers)o();this.unsubscribers=[]}render(){return he(e,{...this.props,...this.state})}},r.displayName=t?.displayName||`WithSignals(${ve(e)})`,r}function Te(e,n,t){return Z(e,{value:n},{displayName:t?.displayName})}export{ge as batch,ce as createComputed,E as createEffect,C as createSignal,fe as flushSync,de as untrack,ye as useSignal,me as useSignalEffect,K as useSignalValue,Te as withSignalValue,Z as withSignals};
