Go-flutter: File dialogs

[ghost]

https://github.com/gen2brain/dlgs

Also has other dialogues and notifications and beeps.

Needed for any desktop app :)

Works on all desktops with only golang

I suppose this could be a neat plugin. It's not required for this library to function. The plugin could be a very nice cross-platform example for plugins with this library.

The use case i have in mind was for when a user needs to save a file or open a file.
For example:

• when you export a report
• want to add an image to an app.

Here is what i have found. It would be good to provide these basics as a plugin for go-flutter-desktop.

dialogs

Flutter-go needs to interact with the Desktop os for:

• Printer dialog, where we send it a PDF to print
• Select File (s) to upload
• Select where to download a file
• Show Notifications
• Other.

Libs Research:

Inputs

https://github.com/gen2brain/dlgs/
dlgs is a cross-platform library for displaying dialogs and input boxes.

• WORKS :)
• All OS's
• No CGO :)
• Select from a list. Not needed as Flutter does that.
• ask question with true false. Again not needed as flutter does that.
• Enter Password. Maybe needed

Notify

https://github.com/gen2brain/beeep
beeep provides a cross-platform library for sending desktop notifications, alerts and beeps.

• WORKS :)
• no CGO :)
• PLay sound. Maybe Needed
• Show Notifications. Needed.
• Show Alerts. Needed.
• 
  
  • For icons to work its needs to be bundled as an App, so it can use the App icon.
  
  

Screenshot.

• WORKS :)
• All OS's
• Uses CGO, which is not so good :( . Maybe look around for other libs.

File

https://github.com/sqweek/dialog

• no cgo. :)
• All Os's :)
• Select Directory to Write to.
• Select File to read form

https://github.com/alexbrainman/printer

Scanning

Scan from the program

• Bring up the scannng dialog

Webview

• Somtimes you need a Webview for whatever reason as part of your desktop app.
• https://github.com/zserge/webview
• Works very well
• On Windows its not using Edge, but old MSHTML, so no Javascript.

systray

• For times when you need a systray running.
• YOu can run a Flutter GUI in the systray. For example the TunnelBear systray is an excellent example.

Thanks for @drdgvhbh 's amazing work.
I have modified @drdgvhbh 's code and provide an example since I really need to use this plugin in my project.
I did an example PR, perhaps you want to check it.

Somewhat related. I've added initial work for a desktop compatibility with Flutter's image_picker.

It can be found here: https://github.com/go-flutter-desktop/plugins/tree/master/image_picker
