에러: Assets must have hashed files. Ensure the expo-asset plugin is installed.

metro.config.js 파일을 추가해서 해결

//metro.config.js
const { getDefaultConfig } = require("@expo/metro-config");
const mergeConfig = require("metro-config").mergeConfig;

const config = {
  transformer: {
    assetPlugins: ["expo-asset/tools/hashAssetFiles"],
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
};

module.exports = mergeConfig(getDefaultConfig(__dirname), config);
