A new Flutter project.

• Core is a common/shared folder

• UI -> Provider -> Repository -> Service

• Don't create any service or repository in any class instead pass the instance through constructor.
• Don't create long build method. Create smaller widget functions or separated stateless widget
• Don't write big functions. Instead create small/modular testable functions.
• Create readable and meaningful file, class, function and variable names.
• Remember your dart file should not have any warning in it.
