Hey 👋 the package used in the pr

• webview_cef

Have Linux support listed as work in progress at pub dev

I suggest using desktop_webview_window as it supports all the 3 platforms - MacOs , Windows and Linux

[mmjsmohit]

@BrawlerXull The package desktop_webview_window has some pre-requisites which are necessary to be installed on the user's machine. We would have to figure out how to install the pre-reqs while API Dash is being installed.

See https://pub.dev/packages/desktop_webview_window#linux-requirement and https://pub.dev/packages/desktop_webview_window#windows

Exactly, this approach also spawns a new webview window, which is not the desired outcome as per the screenshot in the original PR.

Shall I close this request or is someone gonna merge it?

[animator]

@monstajoe2002 It takes time to review and merge PRs. Please be patient.

I found webview_universal, which should supposedly work on Linux. However, it creates a separate window for that HTML page. Is that OK for you?

[animator]

@monstajoe2002 Please add preview (screenshot) for the test case given here

[monstajoe2002]

Here's the result after using webview_universal

[animator]

@monstajoe2002 Ahh it opens in a new window. This won't work as it will lead to poor user experience.

[animator]

@monstajoe2002 If a solution works for macOS & Windows and does not work for Linux, it is acceptable. We can raise an improvement issue to add support for Linux for that feature so that the community can work on it and add it when it is available.

[monstajoe2002]

Exactly. Do note that I had to modify main.cpp (Desktop binary) in the windows directory on Windows to get it working according to the webview_cef documentation. This is ignored by git by default.

[animator]

One issue with webview_cef is that the build size will increase drastically due to chromium binary. Is there any other alternative?

[monstajoe2002]

So far, no. How drastic are we talking?

[monstajoe2002]

Why did you close #165?

[animator]

So far, no. How drastic are we talking?

Adding ~200 MB just to add this feature is an overkill. The current size is ~30 MB.

Why did you close #165?

As the package used did not provide the desired result.
