Flutter Builds Script 🧑‍💻

Making it easier to generate all flutter builds.

Description

This script automates Flutter project builds with flavor and type options. It allows you to customize the number of flavors, flavor names, entry points, and build types.

Prerequisites

• Flutter installed and configured.
• Bash shell environment.

Demo for - release_builds.sh

demo.mp4

Options

• --use-defaults: Use default values.
• --no-flavor: Build without flavors.

Usage

• Default:

  ./release_builds.sh

• For zsh:

  sh release_builds.sh

Additional Points

• The script allows you to customize the number of flavors, flavor names, entry points, and build types.
• Use --use-defaults for quick builds with default values.
• Use --no-flavor if you don't want to use flavors. In this case, the script will prompt you to select build types directly.
• The script creates timestamped build directories in the /builds folder.
• Open the latest build directory automatically using open builds/$current_date_time.
