Overview

PUBM, short for Pubspec Manager, is a Dart-Command Line tool created to manage multiple versions of pubspec.yaml files in a single project. This tool helps in merging multiple pubspec.yaml files into a single pubspec.yaml file as per the selected flavor.

📋 Installation

To install the pubm package, add it as a new dev dependency in your pubspec.yaml file. Run the following command in your terminal:

PS c:\src\flutter_project> dart pub add --dev pubm

For Flutter projects, use:

PS c:\src\flutter_project> flutter pub add --dev pubm

🎯 Activate from https://pub.dev

to use the executable, run the following command in your terminal:

dart pub global activate pubm

📋 Usage

To manage different versions of pubspec.yaml files, create a new file for each flavor with the name pubspec_<flavor>.yaml. When the following command is executed, the pubspec.yaml file is updated with the contents of the pubspec_<flavor>.yaml file. This can be used to update, change, or add dependencies and their respective versions, as well as Flutter fonts.

# if activated from https://pub.dev
pubm -f <flavor>

# else
dart run pubm:manage -f <flavor>

Use the -v flag to print detailed logs (verbose logs) in the console.console.

# if activated from https://pub.dev
pubm -f <flavor> -v

# else
dart run pubm:manage -f <flavor> -v

📋 Example: pubspec_dev.yaml

Here's an example of a flavor-specific pubspec.yaml file for a 'dev' flavor:

description: dev version of pubspec.yaml
version: 0.0.1-dev

dependencies:
  example_dependency: 
   path: example/dependency

dev_dependencies:
  lints: ^2.1.1
  

flutter:
  fonts:
    - family: font1
      fonts:
        - asset: dev/font1/700.ttf
          weight: 700
        - asset: dev/font1/600.ttf
          weight: 600
        - asset: dev/font1/500.ttf
          weight: 500
        - asset: dev/font1/400.ttf
          weight: 400
    - family: font2
      fonts:
        - asset: dev/font2/700.ttf
          weight: 700
        - asset: dev/font2/600.ttf
          weight: 600
        - asset: dev/font2/500.ttf
          weight: 500
        - asset: dev/font2/400.ttf
          weight: 400

The above values present in the pubspec_

📋 Example: pubspec.yaml

Here's an example of the main pubspec.yaml file:

name: pubm
description: Actual description
version: 0.0.1

environment:
  sdk: ^3.0.0

dependencies:
  cupertino_icons: ^1.0.2

flutter:
  uses-material-design: true
  generate: true
  fonts:
    - family: font1
      fonts:
        - asset: actual/font1/700.ttf
          weight: 700
        - asset: actual/font1/600.ttf
          weight: 600
        - asset: actual/font1/500.ttf
          weight: 500
        - asset: actual/font1/400.ttf
          weight: 400
    - family: font2
      fonts:
        - asset: actual/font2/700.ttf
          weight: 700
        - asset: actual/font2/600.ttf
          weight: 600
        - asset: actual/font2/500.ttf
          weight: 500
        - asset: actual/font2/400.ttf
          weight: 400

After running the below command, the output pubspec.yaml file will be as follows:

Command:

# if activated from https://pub.dev
pubm -f dev

# else
dart run pubm:manage -f dev

Output

name: pubm

version: 0.0.1-dev

environment:
  sdk: ^3.0.0

dependencies:
  # normal dependencies
  cupertino_icons: ^1.0.2
  # path related dependencies
  example_dependency: 
   path: example/dependency

dev_dependencies:
  # normal dev_dependencies
  lints: ^2.1.1

flutter:
  uses-material-design: true
  generate: true
  fonts:
    - family: font1
      fonts:

📋 Example: Removing values from pubspec.yaml

To remove a dependency from the pubspec.yaml file, add the following line to the pubspec_

To remove dependency from dependencies section: add it to the dependencies section of the pubspec_

the same with dev_dependencies and dependency_overrides section.

Remove section should have the same format of the yaml file.

After going through all the updating values, it will look for the remove section, if found it will look into the data and remove respective form the actual pubspec.yaml file.
