want to show more data in another component when view in detail button is clicked (angular 6)

Create a data sharing service first, here's sample code, you should modify according to your need

Data sharing service

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs/BehaviorSubject';

@Injectable()
export class DataSharingService {
    private title = new BehaviorSubject<string>("");
    currentTitle = this.title.asObservable();

    setTitle(txt: string){
        this.title.next(txt);
    }
}

inject this service into your incident component

Data sender component

constructor(
    private dataSharingService: DataSharingService
  ) { }

use this service where you want in your incident component before navigation

this.dataSharingService.setTitle("Your title or data");

Now you surely want to receive data into your incident detail component, for that here's sample code

Data receiver component

title: string;
  constructor(private dataSharingService: DataSharingService ) { }

  ngOnInit() {
    this.dataSharingService.currentTitle.subscribe(data => {
      this.title = data;
    })
  }

Note: Please modify according to your requirement, this service I made to set and get string title. This service is useful for independent components, without any child-parent relationship.
