Checkbox angular material checked by default

Question

I am trying to use an Angular Material checkbox, and set it by default as checked, but it is displayed as non-checked, what is wrong?

Answer 1

You can use

if the checked attribute is set to null, it gets removed from the html tag

or you can use Vega's anwser which should work too (mine is a completion that can be usefull if you don't want to link it with ngModel)
