Below is My Date Range Component HTML:
<mat-form-field appearance="fill" class="fields-full-width">
<mat-label>Enter a date range</mat-label>
<mat-date-range-input
[rangePicker]="picker"
[dateFilter]="rangeFilter"
formGroupName="dateRange"
>
<input
matStartDate
placeholder="Start date"
formControlName="start"
autocomplete="off"
/>
<input
matEndDate
placeholder="End date"
formControlName="end"
autocomplete="off"
/>
</mat-date-range-input>
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-date-range-picker #picker></mat-date-range-picker>
</mat-form-field>
For [dateFilter]="rangeFilter"
I have added below function in my component:
rangeFilter(date: Date): boolean {
return date.getDate() > 20;
}
My package.json file:

But the error I am getting:
(date: Date) => boolean' is not assignable to type 'DateFilterFn
I tried my all possible way. But getting this error. Your valuable suggestion is needed.
According to MatDateRangeInput
dateFilter
Input property,
@Input()
dateFilter: DateFilterFn<D>
type DateFilterFn = (date: D | null) => boolean;
Hence change the rangeFilter
's method signature as below:
import { DateFilterFn } from '@angular/material/datepicker';
rangeFilter: DateFilterFn<Date> = (date: Date | null) => {
// Implementation
return date?.getDate() > 20;
};
