We want to use one of your buttons...

<mdb-icon far icon="dot-circle"></mdb-icon>

but we want to set the far/fas value programmatically...

<mdb-icon {{getFarFas(row.value)}} icon="dot-circle"></mdb-icon>

There are four different conditions... for two we want far and for the other two we want fas…

  getFarFas(circleCode : number) {
    switch(circleCode) {
      case(0) : {
        return `far`;
      }
      case(1) : {
        return `far`;
      }
      case(2) : {
        return `fas`;
      }
      case(3) : {
        return `fas`;
      }
    }
  }

we are getting ERROR DOMException: "String contains an invalid character"
