Update
try requesting another endpoint to see if the problem is in your local server, try this:
var url = "https://jsonplaceholder.typicode.com/todos/1";
final response= await http.get(url);
print(response.statusCode);
if it worked then the problem is server-side.
Old Answer
If it's giving you StatusCode 400 then it means that the server is working fine, so probably the problem is in the request itself, try adding headers to your request.
await http.get(url, headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
);
if this was not the issue, can you please add the error message!
