How to pass BuildContext without 'JsObject' error in Flutter?

Question

I'm developing a Flutter application and encountered an issue when trying to use the showDialog function. The compiler throws an error stating that the argument type 'JsObject' can't be assigned to the parameter type 'BuildContext'. I suspect the issue arises from a misunderstanding of how to correctly pass the BuildContext or possibly due to an incorrect import.

Error Message:

 The argument type 'JsObject' can't be assigned to the parameter type
 'BuildContext'.

What I've tried:

1. Removing the import dart:js; line, thinking it might be causing conflicts with the BuildContext type.

2. Aliasing the import as context using import 'dart:js' as context;, but the issue persists.

3. Considering passing the BuildContext explicitly or using a null assertion operator (!), but I'm unsure if that's the right approach or how to properly implement it.

Code Snippet:

import 'dart:js';

import 'package:flutter/material.dart';

showDataAlert() {
  showDialog(
      context: context,
      builder: (context) {
        return AlertDialog(
           // AlertDialog content
        );
      });
}

Questions:

• How should I correctly pass the BuildContext to showDialog to avoid this type conflict?
• Is the import 'dart:js'; line relevant to this issue, and how should I handle it if so?
• Are there best practices for using BuildContext in such scenarios that I might be overlooking?

I have searched Stack Overflow for similar issues but found none that address the specific type mismatch error with BuildContext and JsObject. I appreciate any guidance on resolving this issue. Thank you in advance!

Answer 1

First delete "import 'dart:js and save the file. then Pass context on method.

showDataAlert(BuildContext context) {

Save again, run the app. If fails do flutter clean and rebuild the app.
