# 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.
