Technologies

Flutter is used in this project, a Cross-platform framework written in Dart, created by Google in 2017. This technology was chosen for its versatility, ease of use, code maintenance and other amenities, and it is on the rise in the world of development.

For the layout of the App, Figma was used.

Google Maps API (Application Programming Interface) is also used to obtain the user's location and map display in the application and Firebase for data storage and user login/SignUp.

With the announcement that Flutter now supports Material You (Material 3) made by Google at Google I/O 2022, it was chosen to use the feature that left the design more modern and minimalist. As Delivery Express was initially developed with Flutter version 2.10.1 it was upgraded to Flutter 3 without much trouble.

App Logo

It's pretty simple, it's the delivery guy with the app's main color with an elevation to give a drop shadow effect.

Colors Used

For the colors, the main color was used from the original design. But with the release of Material 3, a tool for harmonizing colors and dynamic colors was launched, the Material Theme Builder.

Primary color is: #B91D1D

So we have as a result:

Fonts Used

The following fonts are currently used in this project:

Montserrat¹
Quick Express²

Where the first is used in every app and in the logo, and the second mentioned is only used in the app logo on the login page, to get dynamics for different screen sizes.
