Steps to reproduce the issue:
My application runs After upgrading ABP from version 7 to 8.1.1, but I cannot see the Flags of LanguageSwitchViewComponent in the UI. How can I fix this? before upgrading

Code from App\aspnet-core\src\Kwork.StaffApp.HttpApi.Host\Themes\Lepton\Layouts\Account\Default.cshtml for custom login page

After upgrading

* When upgrading, the flags file is automatically deleted. I try to recover but the flag is still hidden. I think 1 function in LanguageSwitchViewComponent is changing and don't use the flag again. So I want to know how to update/ fix the current LanguageSwitchViewComponent

Hello,

Can you please refer to this link: https://github.com/abpframework/abp/issues/13024

We do not have that feature (flag icons) in the latest (7.3.2 onwards) version of ABP.

regards,

Thank you, but with the updated version, we can't see the flag, hard to click the change language button, and don't know what is the current language.

Do you have any Ideas/suggestions to fix these issues?

Thank you

Hi, flag-icons are removed from ABP Framework & Lepton themes.

Here was the diff from the removal operation:

If you still want to use, you can override the following component: /Themes/Lepton/Components/Toolbar/LanguageSwitch/Default.cshtml and re-apply this changes.

And don't forget to add abp/flag-icon-css dependency into your packages.json:

"@abp/flag-icon-css": "~7.4.5",

I also check here, but maybe not right for Lepton/Theme component. https://github.com/abpframework/abp/blob/rel-7.1/modules/basic-theme/src/Volo.Abp.AspNetCore.Mvc.UI.Theme.Basic/Themes/Basic/Components/Toolbar/LanguageSwitch/Default.cshtml

Please help me for LanguageSwitch/Default.cshtml origin code - version 7.1

Hi,

I also updated the file /LanguageSwitch/Default.cshtml, reverted the flag-icons folder, and installed the flag-icon package in Angular. But the flag is still not displayed. What I'm missing for setup now?

Thank you,

If you have source-code access, you can download source-code of lepton via the following command:

abp get-source Volo.Abp.LeptonXTheme.Pro

Also I can share with you the previous version with flags: Themes/Lepton/Components/Toolbar/LanguageSwitch/Default.cshtml:

@using Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Themes.Lepton.Components.Toolbar.LanguageSwitch
@using Microsoft.AspNetCore.Http.Extensions
@model LanguageSwitchViewComponentModel
@if (Model.OtherLanguages.Any())
{
    <div class="dropdown">
        <a class="btn dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            @if (@Model.CurrentLanguage.FlagIcon != null)
            {
                <span class="fi fis fi-@Model.CurrentLanguage.FlagIcon" data-bs-toggle="tooltip" title="@Model.CurrentLanguage.DisplayName" role="tooltip"></span>
            }
            else
            {
                <span class="fi fis fi-@Model.CurrentLanguage.CultureName" data-bs-toggle="tooltip" title="@Model.CurrentLanguage.DisplayName" role="tooltip"></span>
            }
            <span class="current-language-name">@Model.CurrentLanguage.DisplayName</span>
        </a>
        <div class="dropdown-menu dropdown-menu-end" aria-labelledby="dropdownMenuLink">
            @foreach (var language in Model.OtherLanguages)
            {
                <a class="dropdown-item" href="~/Abp/Languages/Switch?culture=@(language.CultureName)&uiCulture=@(language.UiCultureName)&returnUrl=@(System.Net.WebUtility.UrlEncode(Context.Request.GetEncodedPathAndQuery()))">
                    @if (language.FlagIcon != null)
                    {
                        <span class="fi fis me-2 fi-@language.FlagIcon"></span>
                    }
                    else
                    {
                        <span class="fi fis me-2 fi-@language.CultureName"></span>
                    }
                    @language.DisplayName
                </a>
            }
        </div>
    </div>
}
