I liked Altus answer, but I would like to have more breakpoints. So I've created a simple method with some breakpoints using FlexLayout ObservableMedia service instead of onResize:

import { AfterContentInit, Component, ViewChild } from '@angular/core';

import { MediaChange, ObservableMedia } from '@angular/flex-layout';
import { MatGridList } from '@angular/material';

@Component({
  selector: 'app-grid',
  templateUrl: './grid.component.html',
  styleUrls: ['./grid.component.css']
})
export class GridComponent implements AfterContentInit {
  @ViewChild('grid') grid: MatGridList;

  gridByBreakpoint = {
    xl: 8,
    lg: 6,
    md: 4,
    sm: 2,
    xs: 1
  }

  constructor(private observableMedia: ObservableMedia) {}

  ngAfterContentInit() {
    this.observableMedia.asObservable().subscribe((change: MediaChange) => {
      this.grid.cols = this.gridByBreakpoint[change.mqAlias];
    });
  }
}

Breakpoint: {{grid.cols}}
