This question got resolved

I put in his code

void getUID() {
  FirebaseAuth auth = FirebaseAuth.instance;
  User? user = auth.currentUser;
  if (user != null) {
    setState(() {
      uid = user.uid;
    });
  }
}

When I run the flutter program I now get this error  msg

======== Exception caught by widgets library =======================================================

Screenshot of my emulator

Using Flutter and Visual Code.

For the 3rd time to whomever looks at this code. The tasklist1page isn't being shifted to the left. People from oneclass keep sending me this same code and it doesn't work. Has anyone actually tested this code on Visual Code? This is making me frustrated? Can someone fix that code below and use the  ``` before and after the code. So I can see it clearly.  Also please attach a screenshot when you reply back so I know you have tested it. Screenshot of the problem below the flutter code.

import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';
import 'package:todolist/pages/tasklist/tasklist.dart';
import 'package:todolist/pages/tasklistdetails/tasklistdetails.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        textTheme: GoogleFonts.robotoCondensedTextTheme(),
      ),
      initialRoute: '/tasklist',
      routes: {
        '/tasklist': ((context) => Scaffold(
              appBar: AppBar(
                title: Container(
                  child: Align(
                    alignment: Alignment.centerLeft,
                    child: Text(
                      "Task List1 Page",
                    ),

                  child: const Icon(Icons.add),

              ),
            )),
        '/tasklistdetails': ((context) =>
            const TaskListDetailsPage(title: "Task List Details Page"))
      },
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: const Text('Task list page'),
      floatingActionButton: Theme(
        data: Theme.of(context).copyWith(splashColor: Colors.amber),
        child: FloatingActionButton(
          onPressed: () => {Navigator.pop(context)},
          tooltip: 'Increment',
          child: const Icon(Icons.add),
        ),
      ),
    );
  }
}

Using latest Flutter and Visual Code. Followed someone suggestion to align the text to the left side but it failed.

Anyway here is the code below

```

Still having problems title not being shifted using TextAlign property. Using Visual Code and Flutter. Visual Code is complaining about it. Here's the code

Also please use the ``` when putting in your code so I can see it clearly since it will be formatted.
