I am at Angular 9, and get this error when building, tested both 2.4.0 and 2.4.1, had to rollback to 2.3.0:

WARNING in Invalid constructor parameter decorator in _[directory]_/node_modules/ng2-charts/fesm2015/ng2-charts.js:
() => []

ERROR in getInternalNameOfClass() called on a non-ES5 class: expected ThemeService to have an inner class declaration

add ThemeService in provider section in app.module.ts, this will resolve this error.

You have to add ThemeService in providers array in your module file. For example :

/app.module.ts/

imports : [
--------],

providers : [ThemeService]

---

/end of module file/

I have included Provide as mentioned above, but still getting below error:
