Description

Describe the bug

Blank Expo 57 project with react-native-echarts fails rendering the chart on RN web with TypeError: tslib.default is undefined with the example from the README. Full reproduction: https://github.com/rabbldating/testrnecharts

To Reproduce

npx create-expo-app@latest --template blank-typescript
cd project
npx expo install @wuba/react-native-echarts echarts react-native-svg
npx expo install react-dom react-native-web

Then add example chart from https://github.com/wuba/react-native-echarts#example

Then:

npx expo start --web

The following error shows up and the chart does not render:

$ npx expo start --web
[...]
Web  ERROR  [TypeError: tslib.default is undefined] @http://localhost:8081/index.ts.bundle?platform=web&dev=true&hot=false&lazy=true&transform.engine=hermes&transform.routerRoot=app&unstable_transformProfile=hermes-stable:30890:7

Research direction

Trace the web bundle error for tslib.default and verify that the example chart renders successfully in Firefox without the TypeError.
