Upgrade to Angular13 fails

When I upgraded to Angular 13 this morning - I started receiving this error

Error: node_modules/ngx-material-file-input/lib/file-input/file-input.component.d.ts:9:22 - error TS2720: Class 'FileInputComponent' incorrectly implements class 'MatFormFieldControl<FileInput>'. Did you mean to extend 'MatFormFieldControl<FileInput>' and inherit its members as a subclass?
  Type 'FileInputComponent' is missing the following properties from type 'MatFormFieldControl<FileInput>': stateChanges, errorState

9 export declare class FileInputComponent extends FileInputMixinBase implements MatFormFieldControl<FileInput>, ControlValueAccessor, OnInit, OnDestroy, DoCheck {

Would it be possible to get this issue fixed within the library?

Had a quick review of your pr @mcaden and it looks good. Would be great if @merlosy could review and merge as this is blocked our upgrade to Angular 13

I can… it feels a bit like hijacking so I don’t think it’s my first choice. I’m not entirely sure the etiquette on this?

What I’ve done in the meantime that is working for me is that my consuming project is using yarn 2 with zero-installs

1. build my fork
2. use yarn pack in the built directory (dist\material-file-input)
3. copy the resulting file to my consuming project
4. remove reference to ngx-material-file-input
5. yarn add ./<packed filename>
6. delete packed file

The packed file is copied into the .yarn/cache folder and gets committed (which is why yarn 2 with zero-installs is a requirement for this approach).

I don’t like it but it packages up my changes without stepping on toes.

I respect the maintainer for this project and appreciate the work done. I also respect he may be super-busy at the moment and this project is a lower priority. Hopefully somebody with write-privileges will be able to approve the PR (or suggest where I might improve it so it can be approved).

Before I publish a fork I want to verify whether the project is abandoned.
