cannot use rating attribute Type 'string' is not assignable to type 'number' when strict templates is enabled

[renomi]

Hey there, thanks for the great component!

If tsconfig.app.json has

"angularCompilerOptions": {
    "strictTemplates": true
  }

And inside any page add the following:

 <ionic-rating-component #rating activeColor="#FFC200" halfStar="true" rating="0"
          (ratingChanged)="onRatingChange($event)">
  </ionic-rating-component>

Running ionic serve will fail with Type 'string' is not assignable to type 'number'.

Hello @renomi , try with this

<ionic-rating-component #rating activeColor="#FFC200" halfStar="true" _[rating]="0"_
          (ratingChanged)="onRatingChange($event)">
</ionic-rating-component>

Another option is to declare a type number variable in the controller:

rate-page.ts

…..
rate : number = 0;
…..
export class RatePage {

    constructor() {
        
    }
}

rate-page.html

<ionic-rating-component #rating activeColor="#FFC200" halfStar="true" rating="{{number}}"
          (ratingChanged)="onRatingChange($event)">
</ionic-rating-component>

Having the same issue. For me as a tmp workaround - remove default value. Disabling strictTemplate for entire project is not a solution for me.
