Fix for Error : mat-form-field must contain a MatFormFieldControl

I had this issue. I imported MatFormFieldModule at my material module, but forgot to add MatInputModule to the imports array:

import {
	MatFormFieldModule,
	MatInputModule 
} from '@angular/material'

@NgModule({
	imports: [MatFormFieldModule, MatInputModule]
})
export class MaterialModule {}

Always keep a separate module that contains all the material things you use.
