flutter to debian

Flutter_to_debian #

A simple command-line application to help you easily bundle your flutter app build into a debian package ready for production.

Overview of our debian packaging 📦 #
This plugin is a tool that builds debian package based on the instructions listed in a debian.yaml file. To get a basic understanding and its core concepts, take a look at the debian documentation. Additional links and information are listed at the bottom of this page.
Flutter debian.yaml example #
Place the YAML file in your Flutter project under <project root>/debian/debian.yaml. (And remember the YAML files are sensitive to white space!) For example:
flutter_app:
command: mega_cool_app
arch: x64
parent: /usr/local/lib
nonInteractive: false

control:
Package: mega-cool-app
Version: 1.0.0
Architecture: amd64
Priority: optional
Depends:
Maintainer:
Description: Mega Cool App that does everything!

#options:
# exec_out_dir: debian/packages

The following sections explain the various pieces of the YAML file.
Flutter app #
This section of the debian.yaml file defines the application that will be packaged into a debian.
flutter_app:
command: mega_cool_app
arch: x64
parent: /usr/local/lib
nonInteractive: false
copied to clipboard
Command
Points to the binary at your project's linux release bundle, and runs when debian package is invoked.
arch
the build architecture of your app.
execFieldCodes
A comma-separated list of field codes for the Exec key in the desktop
file.
Example: execFieldCodes: f,u,i
Supported codes: f, F, u, U, i, c, k
Further information is available in the FreeDesktop
spec.
parent
the app will be installed in a subdirectory (like mega_cool_app) in this
directory.
nonInteractive #
When true, no prompt for confirmation is displayed during package installation.
default: /opt
Example:
parent: /usr/local/lib
the target directory is: /usr/local/lib/mega_cool_app
Package maintainer scripts #
If the debian/scripts directory exists, executable files named
preinst, postinst, prerm and postrm in debian/scripts will be
copied to the package, as debian package maintainer scripts.
Note that any preinst script with overwrite the one generated by
default by this tool, effectively disabling the interactive confirmation
prompt shown before installation (as if nonInteractive: true was
used).
Additional files: #
If a directory debian/skeleton exists that files will be copied into the package.
This can be used for default configuration files.
Example:
The file debian/skeleton/etc/megacool/main.conf will be installed as /etc/megacool/main.conf
Control #
This is what describes to the apt package manager or what ever piece of software you are using to install your app what it's all about.
Depends
List the libraries your project depends on and they will be installed by the apt package manager before your app in installed on the system.
For example:

the pub.dev package flutter_secure_storage linux version depends on
libsecret-1-0 and libjsoncpp1

NB: more than one Depends are separated by " , " .
Desktop file and icon 🖥️ #
Desktop entry files are used to add an application to the desktop menu. These files specify the name and icon of your application, the categories it belongs to, related search keywords and more. These files have the extension .desktop and follow the XDG Desktop Entry Specification.
Flutter mega-cool-app.desktop example #
Place the .desktop file in your Flutter project under <project root>/debian/gui/mega-cool-app.desktop.
Notice: icon and .desktop file name must be the same as your app name in yaml file!
For example:
[Desktop Entry]
Version=1.0
Name=Mega Cool App
GenericName=Mega Cool App
Comment=A Mega Cool App that does everything
Terminal=false
Type=Application
Categories=Utility
Keywords=Flutter;share;files;
copied to clipboard
Place your icon with .png extension in your Flutter project under <project root>/debian/gui/mega-cool-app.png.

install flutter_to_debian if not done yet.
$ dart pub global activate flutter_to_debian
copied to clipboard
Run flutter_to_debian as follows.
$ flutter_to_debian

Dependency Finder #
The command flutter_to_debian can be used to find the dependencies of an amount of library files.

<mode>:
help
Print this usage.
create
Creates a folder and template files for the Debian package.
build
Build a Debian package file *.deb. This is the default mode.
dependencies [<opts>] [<file1> [ <file2>...]]
Detects the dependencies of a amount of library files.
<fileX> can be a file or a directory.
<opts>:
--excluded-packages=<comma-separated-list-of-names>
That packages will be excluded from detection
--excluded-libraries=<pattern>
Excludes that library files from detection. <pattern> is a regular expr.
Examples:
flutter_to_debian
Creates the Debian package described in ./debian/debian.yaml
flutter_to_debian dependencies
Detects the dependencies of the files in ./build/linux/x64/release/bundle/lib
and uses the information of debian/debian.yaml
flutter_to_debian dependencies --excl-lib=-dev|^my_lib release/libs
Detects the dependencies of the files in release/libs without the excluded
specified by "-dev|^my_lib":
The file release/libs/our_lib-dev.2.so and release/libs/my_lib-dev.2.so
will be excluded from detection.
flutter_to_debian dependencies --excluded-packages=lintian,my-project prod/libs
