The getter 'documents' isn't defined for the type 'QuerySnapshot<Object?>'

Question

var capitalValue = value.substring(0,1).toUpperCase() + value.substring(1);

    if(queryResult.length == 0 && value.length == 1) {
       SearchService().searchProduct(value).then((QuerySnapshot docs){
         for(int i = 0; i < docs.documents//here error .length; i++) {
           queryResult.add(docs.documents//here error [i].data);
         }
       });
    }
    else{
      tempSearch = [];
      queryResult.forEach((element) {
        if(element['category'].startsWith(capitalValue)) {
          setState(() {
            tempSearch.add(element); 
          });
        }
      });
    }
  }

I think you are following some old documentation or tutorial. As far as I remember, object of QuerySnapshot has been changed few months ago.

They have simplified the usage by changing documents to docs and document to doc.

So your code should be like this

SearchService().searchProduct(value).then((QuerySnapshot docs){
   for(int i = 0; i < docs.docs.length; i++) {
      queryResult.add(docs.docs[i].data);
   }
});
