Metadata |
This section of the snapcraft.yaml file defines and |
describes the application. The snap version is |
derived (adopted) from the build section.<topic_end> |
<topic_start> |
Grade, confinement, and base |
This section defines how the snap is built.<topic_end> |
<topic_start> |
Apps |
This section defines the application(s) that exist inside the snap. |
There can be one or more applications per snap. This example |
has a single application—super_cool_app.When a providing snap is installed, snapd will |
generate security policy that will allow it to |
listen on the well-known DBus name on the specified |
bus. If the system bus is specified, snapd will also |
generate DBus bus policy that allows ‘root’ to own |
the name and any user to communicate with the |
service. Non-snap processes are allowed to |
communicate with the providing snap following |
traditional permissions checks. Other (consuming) |
snaps might only communicate with the providing |
snap by connecting the snaps’ interface.<topic_end> |
<topic_start> |
Parts |
This section defines the sources required to |
assemble the snap.Parts can be downloaded and built automatically using plugins. |
Similar to extensions, snapcraft can use various plugins |
(such as Python, C, Java, and Ruby) to assist in the |
building process. Snapcraft also has some special plugins.<topic_end> |

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 version 1.1.<topic_end> |
<topic_start> |
Flutter super-cool-app.desktop example |
Place the .desktop file in your Flutter project |
under <project root>/snap/gui/super-cool-app.desktop.Notice: icon and .desktop file name must be the same as your app name in |
yaml file!For example:Place your icon with .png extension in your Flutter |
project under <project root>/snap/gui/super-cool-app.png.<topic_end> |
<topic_start> |
Build the snap |
Once the snapcraft.yaml file is complete, |
run snapcraft as follows from the root directory |
of the project.To use the Multipass VM backend:To use the LXD container backend:<topic_end> |
<topic_start> |
Test the snap |
Once the snap is built, you’ll have a <name>.snap file |
in your root project directory.$ sudo snap install ./super-cool-app_0.1.0_amd64.snap –dangerous<topic_end> |
<topic_start> |
Publish |
You can now publish the snap. |
The process consists of the following:<topic_end> |

Snap Store channels |
The Snap Store uses channels to differentiate among |
different versions of snaps.The snapcraft upload command uploads the snap file to |
the store. However, before you run this command, |
you need to learn about the different release channels. |
Each channel consists of three components:<topic_end> |
<topic_start> |
Snap Store automatic review |
The Snap Store runs several automated checks against |
your snap. There might also be a manual review, |
depending on how the snap was built, and if there are |
any specific security concerns. If the checks pass |
without errors, the snap becomes available in the store.<topic_end> |

<topic_start>Build and release a Windows desktop app |
One convenient approach to distributing Windows apps |
is the Microsoft Store. |
This guide provides a step-by-step walkthrough |
of packaging and deploying a Flutter app in this way.info Note |
You are not required to publish Windows apps through the |
Microsoft Store, particularly if you prefer more control |
over the distribution experience or don’t want to deal |
with the certification process. The Microsoft documentation |
includes more information about traditional installation |
approaches, including Windows Installer.<topic_end> |

Preliminaries |
Before beginning the process of releasing |
a Flutter Windows desktop app to the Microsoft Store, |
first confirm that it satisfies Microsoft Store Policies.Also, you must join the |
Microsoft Partner Network to be able to submit apps.<topic_end> |

Set up your application in the Partner Center |
Manage an application’s life cycle in the |
Microsoft Partner Center.First, reserve the application name and |
ensure that the required rights to the name exist. |
Once the name is reserved, the application |
will be provisioned for services (such as |
