1.Setup Flutter Project12:09
2.Setup Material Route12:44
Learn to set up material route navigation in flutter by creating a home screen and an employee screen, wired with a route generator that maps routes and a no-route screen.

4.Extract TextFormField Widget10:23
5.Setup Date Picker11:59
6.Custom Date Format.mp45:26
7.Refactor Date Picker Form Field7:16
8.Create Database Table4:10
Create an employee table in Flutter using Drift for SQLite by defining an employee entity with id auto-increment key and columns for username, first name, last name, date of birth.
9.Create Database8:15
10.Write Database Query11:05
Write queries to get, update, and delete records in a Flutter SQLite database. Retrieve all employees or an employee by ID, and perform insert, update, and delete operations using companions.
11.Insert Employee To Database12:47
12.Dispose Database and TextEditingController3:42
Learn to properly dispose a Flutter SQLite database and its TextEditingController instances, closing the database and releasing resources to prevent memory leaks and boost app performance.
13.Get Employee List12:13
14.Card Design5:49
Reformat the card design in Flutter by adjusting elevated borders, border side, width, and radius, set text color and padding, and align content to start while testing color variations.
15.Get Single Employee12:32
16.Update Employee4:17
17.Delete Employee4:20
Employee Stream Method1:31
Implement a get employees stream to return the list of employee data from the employee table as a stream, using a watch mechanism and avoiding async.
18.Form Validation8:28
Learn how to validate a form in Flutter using a form key and a global key, show error messages for empty fields, and only save when validation passes.
19.Bottom Navigation Bar12:43

20.Singleton Using Provider Package13:20
Create a single app database instance with the provider package to enforce a global singleton. Wire disposal and manage add, edit, delete, and stream versus future operations.
21.Create ChangeNotifier - I9:09
Create a change notifier to update the UI on data changes, wiring an RSA employee notifier to the database, exposing an employee list via a stream and listening for updates.
22.Create ChangeNotifier - II12:28
23.ChangeNotifierProxyProvider6:50
Explore building a Flutter SQLite database app using ChangeNotifierProxyProvider within a multi provider setup to manage employee data, initialize the database, and dynamically update employee details.

28.More on Provider read - watch - select9:30
30.Provider Consumer Widget5:28
31.Provider Selector Widget9:58
Explore the provider selector widget as an efficient alternative to consumer, filtering updates to a selected value and rebuilding only when that value changes, with practical employee data examples.

39.Address Table And Migration11:28
Create a new employee address entity with auto-increment id, street and country, and cascade delete; perform a two-to-three migration using before open to enable foreign keys.

Address Query5:41
Address ChangeNotifier12:16
Address ChangeNotifierProxyProvider4:39
Insert Address Method3:51
Provider Listener10:05
Learn how to set up a provider listener for address changes, initialize change notifiers, add listeners, handle errors, and test migrations in a Flutter SQLite app.
Fix No Table Found Exception1:36
Address Screen8:26
Address By Employee10:18
Delete Address and Employee4:19

Basic of Flutter & Dart

Description

In this Flutter course we are going to learn about local data storage using drift package which help us to create and write SQL query more easily, it internally make use of SQLite 3 and work well both with Android and iOS.

We will able learn about Flutter state management using Provider package which is really popular among Flutter developers. We will cover basic to advance state management using Provider package.

By using provider instead of manually writing InheritedWidget, you get:

simplified allocation/disposal of resources
lazy-loading
a vastly reduced boilerplate over making a new class every time
devtool friendly – using Provider, the state of your application will be visible in the Flutter devtool
a common way to consume these InheritedWidgets (See Provider.of/Consumer/Selector)
increased scalability for classes with a listening mechanism that grows exponentially in complexity (such as ChangeNotifier, which is O(N) for dispatching notifications).

Drift is a reactive persistence library for Flutter and Dart, built on top of sqlite. Drift is

Flexible: Drift let's you write queries in both SQL and Dart, providing fluent apis for both languages. You can filter and order results or use joins to run queries on multiple tables. You can even use complex sql features like WITH and WINDOW clauses.
Feature rich: Drift has builtin support for transactions, schema migrations, complex filters and expressions, batched updates and joins. We even have a builtin IDE for SQL!
Modular: Thanks to builtin support for daos and imports in sql files, drift helps you keep your database code simple.
Safe: Drift generates typesafe code based on your tables and queries. If you make a mistake in your queries, drift will find it at compile time and provide helpful and descriptive lints.
Fast: Even though drift lets you write powerful queries, it can keep up with the performance of key-value stores. Drift is the only major persistence library with builtin threading support, allowing you to run database code across isolates with zero additional effort.
Reactive: Turn any sql query into an auto-updating stream! This includes complex queries across many tables
Cross-Platform support: Drift works on Android, iOS, macOS, Windows, Linux and the web. This template is a Flutter todo app that works on all platforms
Battle tested and production ready: Drift is stable and well tested with a wide range of unit and integration tests. It powers production Flutter apps.
