# Photo Search app
|
|
|
|
|
|
|
|
|
|
This desktop application enables you to search
|
|
|
|
|
[Unsplash](https://unsplash.com/) for photographs that interest you.
|
|
|
|
|
To use it, you need to add an **Access Key** from
|
|
|
|
|
[Unsplash API](https://unsplash.com/developers) to
|
|
|
|
|
`lib/unsplash_access_key.dart`.
|
|
|
|
|
|
|
|
|
|
This sample works on Windows, macOS and Linux.
|
|
|
|
|
|
|
|
|
|
## A quick tour of the code
|
|
|
|
|
|
|
|
|
|
This Flutter project builds a desktop application. It utilises the following
|
|
|
|
|
desktop specific plugins:
|
|
|
|
|
|
|
|
|
|
- [fluent_ui] for the Fluent UI widget set
|
|
|
|
|
- [file_chooser] to enable the application user to select where to save a photo
|
|
|
|
|
from the Unsplash API.
|
|
|
|
|
- [menubar] for exposing Image Search functionality through the menu bar.
|
|
|
|
|
- [url_launcher] to open external links.
|
|
|
|
|
|
|
|
|
|
The Unsplash API client entry point is in the [Unsplash] class, and is built
|
|
|
|
|
atop [http], [built_value] and [built_collection] for JSON Rest API access.
|
|
|
|
|
|
|
|
|
|
## Deploying to the Microsoft Store
|
|
|
|
|
|
|
|
|
|
This sample uses Yehuda Kremer's [MSIX pub package] to bundle up the Windows
|
|
|
|
|
release build for distribution to the [Microsoft Store]. Microsoft maintains
|
|
|
|
|
a [plethora of documentation][ms_store_publishing_doc] on deploying to the
|
|
|
|
|
Microsoft Store.
|
|
|
|
|
|
|
|
|
|
See the `msix_config` stanza in this sample's `pubspec.yaml` for an
|
|
|
|
|
example configuration. Make sure the `display_name`, `publisher_display_name`,
|
|
|
|
|
`publisher` and `identity_name` attributes match the settings in your
|
|
|
|
|
Microsoft Partner Center application submission.

## macOS Network and File entitlements
|
|
|
|
|
|
|
|
|
|
To access the network, macOS requires applications enable the
|
|
|
|
|
[com.apple.security.network.client entitlement][macOS-client]. For this
|
|
|
|
|
sample, this entitlement is required to access the Unsplash API.
|
|
|
|
|
|
|
|
|
|
Likewise, to save a Photo to the local file system using the `file_chooser` plugin requires the
|
|
|
|
|
[com.apple.security.files.user-selected.read-write entitlement][macOS-read-write].
|
|
|
|
|
|
|
|
|
|
Please see [macOS Signing and Security][macOS-security] for more detail.
