I converted Angular 4 project to Angular 7. ng serve commands works but after login in an application, it gives error in console "Unexpected value 'DataTableModule' imported by the module 'DashboadModule' . Please add a @NgModule annotation." Application works fine in Angular 4 version. I already have DatatableModule in Imports array definition then what is reason of error coming.
If I ng build --prod. it gives below error -
ERROR in Error during template compile of 'DataTableModule' Function calls are not supported in decorators in 'NgModule' 'NgModule' calls a function at @angular\core\core.ts(194,50).
Here DashboardModule is custom module and DataTableModule is NPM module imported in Dashboard.module.ts. Below is definition -
1) dashboard.module.ts
import { NgModule } from '@angular/core';
import { DashboardComponent } from './dashboard.component';
import { DashboardRoutingModule } from './dashboard-routing.module';
import { SharedModule } from './../shared/shared.module';
import { DataTableModule } from 'angular-4-data-table-bootstrap-4';
import { CommonModule } from '@angular/common';
import { DashboardService } from './../shared/_services/dashboard.service';
@NgModule({
imports: [
SharedModule,CommonModule,DataTableModule,
DashboardRoutingModule
],
declarations: [
DashboardComponent
],
providers:[DashboardService]
})
export class DashboardModule { }
2) package.json dependencies
Here version I am using for datatable is - "angular-4-data-table-bootstrap-4": "^0.2.0",
"dependencies": {

}
3) dashboard.component.ts
I imported below definition from DataTableModule
import { DataTable, DataTableResource, DataTableTranslations, DataTablePagination } from 'angular-4-data-table-bootstrap-4';
I also verfied its latest version in NPM repository - https://www.npmjs.com/package/angular-4-data-table-bootstrap-4 it is latest and since last 2 years, no latest release at all. I am worried is there any major changes in Angular 7 about module declaration or definition? If yes, what are those? and how to proceed to fix above issue?
I think this would work.
In app.module.ts:
Just replace:
import { DataTableModule } from 'angular-4-data-table';
with
import { DataTableModule } from 'angular-4-data-table/src/index';
