Is there any way I can pass dynamic data to a component in Angular?

Question

I am trying to pass data that is dynamic to a child component. But I always get the data as undefined in the child component. Below is what I am doing.

ParentComp

Answer 1

if you are sure that your service gets data successfully so this will work :

in the html of your parent component add the quotes :

in your child component , you will check changes of your Inputusing the OnCh:

ngOnChanges(changes: SimpleChanges) {   
   for (let propName in changes) {
      // when your @Input value is changed  
      if(propName === "dataNeeded"){
          console.log(dataNeeded);
      }
   }
}

Hope this would help :)
