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.`)}Ee();function D(e){let[n,t]=(0,u.useState)(()=>e.get());return(0,u.useEffect)(()=>(t(e.get()),e.subscribe(()=>t(e.get()))),[e]),n}function ne(e){let[n]=(0,u.useState)(()=>{let r=typeof e=="function"?e():e;return S(r)});return[D(n),n.set.bind(n)]}var g=require("react");var T=new WeakMap;function te(e,n=[]){let t=(0,g.useRef)({}),r=(0,g.useRef)(null),i=(0,g.useRef)(null);(0,g.useEffect)(()=>{let s=()=>{if(!T.get(t.current)){T.set(t.current,!0);try{r.current&&(r.current(),r.current=null);let o=e();typeof o=="function"&&(r.current=o)}finally{T.set(t.current,!1)}}};return i.current=v(s),()=>{r.current&&r.current(),i.current&&i.current(),T.delete(t.current)}},n)}var ie=pe(require("react")),ae=require("react/jsx-runtime");function re(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 I(e,n,t){var r;return r=class extends ie.default.Component{constructor(o){super(o);this.unsubscribers=[];this.state=re(n)}componentDidMount(){this.unsubscribeAll(),this.setState(re(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(0,ae.jsx)(e,{...this.props,...this.state})}},r.displayName=t?.displayName||`WithSignals(${Ve(e)})`,r}function oe(e,n,t){return I(e,{value:n},{displayName:t?.displayName})}
