是的，prefetch就是先加载到本地缓存，下次可以读取缓存，加载速度会快一点

prefetch 是不是安卓兼容的不好 Image.prefetch(imageUrl) .then(data => { console.log('prefetch success', data); const source = Image.resolveAssetSource({uri: imageUrl}); console.log(`source Uri: ${source.uri}`); if (source && source.uri.startsWith('file://')) { setImageSrc(source.uri); console.log('Image is cached'); } else { console.log('Image is not cached'); } }) .catch(e => { console.log('prefetch error', e); }); 我一直打印 Image is not cached
