If you try data['location'] and it says "method [ ] can’t be unconditionally invoked because the receiver can be null", or after adding an exclamation mark it still says the operator [ ] is not defined for Object type, use the following statements could help
Map data = { }; // declare an empty Map object therefore it cannot be null
data = as Map;

In 2022 for the latest version of flutter it will be a lot of error with the null safety. Here is how to fix it:
First put this at the top: import 'dart:convert';
then change the following lines:
class _HomeState extends State<Home> {
Map data = {};
Object? parameters;

@override
Widget build(BuildContext context) {
parameters =
Map data =

To solve problems for new dart version add at the top:
import 'dart:convert';

and then change the following lines:


class _HomeState extends State<Home> {
Object? parameters;

@override
Widget build(BuildContext context) {
parameters =
Map data =

Then you can use data in the widgets withour problems.

When trying to use Navigator to go to the home screen, I'm getting a "Don't use 'BuildContext's across async gaps."

The code works fine when i first start it up (in chrome), but if I Hot Restart, I get tons of errors, starting with:
"Expected a value of type 'Map<dynamic, dynamic>', but got one of type 'Null'"

Apparently, the "arguments" are null when I navigate to Home. What has changed in newer flutter?

Edit: It's because when I used Hot Restart, the app was still on the Home page, not the Loading page.

Thank you the net ninja. Please is there a way to pass a hole object from one route to another instead of passing single data seperatly??

Thank you very much sir, good lessons for beginners

I have a doubt. Why does the edit location goes into the center, when we add row property into the Scaffold Widget.

[dovidsamuels]

In general is it bad to design positioning using px values? Is it better to use relative scaling? How would this app look on a tiny vs huge device?

[yandelyano]

Thank you for your course.
Kindly remember putting the links to packages, you seem to forget that.

My Code is running but when i tried
try{
as Map;
print("---");
print(data);
print("---");
}
catch(e){
print("Home.dart error: $e");
}

the data is print with no problem but the error are printed as well it said
Home.dart error: Expected a value of type 'Map<dynamic, dynamic>', but got one of type 'Null'

So there's a split second when the loading pages are red(error) then it switch to home page with berlin write on it
