Delete a Row

Catalyst Flutter SDK enables you to delete a single row from a specific Data Store table. However, you will not be able to delete multiple rows at a time. You can delete a row from a table by fetching the row instance and passing it to the delete() method.

The <ROW_INSTANCE> used in the code syntax below is the instance defined in the Row Instance page.

    

        
copy
        

            

        
    
    

         <ROW_INSTANCE>.delete(
    void Function() onSuccess,
 void Function(ZCatalystException) onFailed
)

    

A sample code snippet with fetching the row instance is shown below:

    

        
copy
        

            

        
    
    

         ZCatalystApp.getInstance()
      .getDataStoreInstance()
      .getTableInstance(identifier: 'Products')
      .getRow(
        id: 2823000000014176, //Fetch the row instance
        onSuccess: (APIResponse response, ZCatalystRow row) {
          row.delete(onSuccess: (APIResponse response) { //Delete the row
            print('Row deleted successfully.'); //Actions to be executed upon a succesful deletion
          }, onFailed: (ZCatalystException exception) {
            print('Exception thrown: $exception'); //Actions to be executed upon failure
          });
        },
        onFailed: (ZCatalystException exception) {
          print('Get Row Failed: $exception'); //Actions to be executed upon failure in fetching the row instance
        },
      );
