When attempting to retrieve sorted data from MatTableDataSource, I used the following code:
this.source = this.dataSource.sortData(this.dataSource.filteredData,this.dataSource.sort);
Unfortunately, I encountered an error message:
Argument of type 'MatSort | null' is not assignable to parameter of type 'MatSort'. Type 'null' is not assignable to type 'MatSort'
I am working with Angular 16.
An issue has been identified where this.dataSource.sort is of type MatSort | null, while the expected type for the second parameter in the sortData method is MatSort.
It is important to verify that this.dataSource.sort is not null before executing the this.dataSource.sortData method.
if (this.dataSource.sort)
this.source = this.dataSource.sortData(this.dataSource.filteredData, this.dataSource.sort);
For more information, you can refer to the API documentation for Angular Material table
