Missing required parameters for [Route: messenger.store] - laravel

Question

Why it gives an error of undefined id, i just changed Route::get to route::post and it says that id is undefined... should i change the way i pass it? is it a correct way of inserting data into database ?
here's the route
Route::post('messenger/store/{id}','MessengerController#store')->name('messenger.store');
View...
{!! Form::open(['method'=>'POST','action'=>['MessengerController#store',$id]]) !!}
<div class="form-group">
{!! Form::text('msg',null,['class'=>'form-control'])!!}
</div>
<div class="form-group">
{!! Form::submit('Send Message',['class'=>'btn btn-primary'])!!}
</div>
{!! Form::close() !!}
index controller from where i pass ID
public function index($id)
{
//
$user=Auth::user();
return view('messenger.index',compact('user','id'));
}

Answer 1

{!! Form::open(['method'=>'POST','action'=>['MessengerController#store',$id]]) !!}
<div class="form-group">
{!! Form::text('msg',null,['class'=>'form-control'])!!}
</div>
<div class="form-group">
{!! Form::submit('Send Message',['class'=>'btn btn-primary'])!!}
</div>
{!! Form::close() !!}
change this.
{!! Form::open(['method'=>'POST','url'=>route('messenger.store',[$id])]) !!}
<div class="form-group">
{!! Form::text('msg',null,['class'=>'form-control'])!!}
</div>
<div class="form-group">
{!! Form::submit('Send Message',['class'=>'btn btn-primary'])!!}
</div>
{!! Form::close() !!}
to this.
Using action is kind of deprecated.
