How to get an ILogger in Composer

Using Umbraco And Getting Started

Umbraco 9
Im trying to use ILogger inside a composer to log some information to the log file. If I register an ILogger with dependency injection inside the constructor, I get the below error:
```
private readonly ILogger _logger;
        public ServerRegistrarComposer(ILogger logger)
        {
            _logger = logger;
        }
```
Error:
```
System.InvalidOperationException: 'Composer StarterKit.Core.Composers.ServerRegistrarComposer does not have a parameter-less constructor.'
```
What is the right way to get an instance of ILogger here?

I was able to get the instance of ILogger and use it like below:

  public class ServerRegistrarComposer : IComposer
    {
        public void Compose(IUmbracoBuilder builder)
        {
            var logger = builder.BuilderLoggerFactory.CreateLogger<ServerRegistrarComposer>();

            logger.LogInformation("Hello!!!");          
        }
    }
