Obtain the filter criteria within the user interface of a Kendo grid

My Kendo grid looks like this:

<kendo-grid
    [data]="gridData"
    [pageSize]="state.take"
    [skip]="state.skip"
    [sort]="state.sort"
    [filter]="state.filter"
    filterable="menu"
    (dataStateChange)="dataStateChange($event)"
>

In the component.ts file, I have the following code:

public dataStateChange(state: DataStateChangeEvent): void {
    this.state = state;
    // Want to extract filter values here 

}

I am trying to get the filter values and field names from the above function in order to pass them to the API for server-side filtering. However, I am having trouble extracting the values from the state object.

Is there a way to extract fields and values from the state object?
