The Issues after upgrading @angular/core to version 2.3.0

[yywf77]

When "@angular/core" is updated to "~20.3.0", InjectFlags has been deprecated. I tried commenting out the InjectFlags-related content in angular-three.mjs, and the program ran, but the gizmo no longer appeared in its own view and instead appeared in the main view. What could be causing this.

angular-three.mjs

import { /**InjectFlags,*/ } from '@angular/core';

get(token, notFoundValue, flags /** = InjectFlags.Default */) {
    const options = {};
    if (typeof flags === 'object') {
        Object.assign(options, flags);
    }
    else {
        Object.assign(options, {
            optional: !!(flags /** & InjectFlags.Optional*/),
            host: !!(flags /** & InjectFlags.Host*/),
            self: !!(flags /** & InjectFlags.Self*/),
            skipSelf: !!(flags /** & InjectFlags.SkipSelf*/),
        });
    }
    if (token === RendererFactory2) {
        return this.ngtEnvInjector.get(token, notFoundValue, options);
    }
    return this.routeEnvInjector.get(token, notFoundValue, options);
}
