Platform Alert Dialogs

Alert Styles

You can specify the buttons listed in the alert dialog by passing alertStyle argument. The package follows the API design on Windows (see the reference of MessageBox win32 API), and it provides following styles:

• Abort, retry and ignore
• Cancel, try again and continue
• OK
• OK and cancel
• Retry and cancel
• Yes and no
• Yes, no, and cancel

Icon Styles

The package also follow the API design of MessageBox on Windows to add icons to the alert dialogs (see the link above). There are several different icons styles but actually four:

• No icon
• Warning icon
• Information icon
• Question icon

Please note that icons are not available on iOS and Android.

Localization

Since the plugin calls native API, if you want to localize buttons like "OK", "Cancel" and so on on Platforms like iOS, macOS and Linux, you have to do some works in your app.

• To localize the button titles on iOS and macOS, add "Localizable.strings" or "Localizable.stringsdict" files in your Xcode project. Visit Apple's official page for localization for further information.
• On Linux, we use gettext to localize apps. Please update the PO files in your projects once you integrate the plugin.

Android apps embeds resources for localized strings. The localized strings files for the project are located under android/src/main/res. Once you need to add new languages, just fork the project and put your files under the folder.

On Windows, the buttons on the message boxes will be in the Windows system language.
