Upgrade to React Native 0.74: Class private methods are not enabled about react-native-releases

[oblador]

You are expected to use the @react-native/babel-preset preset on react native projects. Either add this one or add @babel/plugin-transform-private-methods as the error suggests.

@oblador I think that @babel/plugin-transform-private-methods is already part of @babel/preset-env. Everything was working prior to the upgrade. Setting all of the plugins to loose mode or configuring them as overrides unfortunately also doesn't solve it.

Based on the upvotes here it seems like other people are facing the same issue :/

[oblador]

It's possible this is related to flow stripping etc too. Could you verify that this is still an issue using the proper @react-native/babel-preset preset? If not, I'd argue that you should either adjust your config or open an issue in the babel monorepo.

@OskarEichler check your babel.config.js or babel.rc file. I was also facing the same issue.

module.exports = {
presets: ['module:@react-native/babel-preset'], <--- this is what you need to resolve your error
plugins: [
'react-native-reanimated/plugin',
],
};
