@saravananmnm Can you provide flutter doctor -v and elaborate on what exactly are you trying to achieve along with expected vs actual behavior ?
Thanks.

@JackJonson Yes. I expect without context is getting errors. But in default constructor doesn't have the required field of context.

@saravananmnm Hi, There is a solution:
If you want to show toast without giving context, must wrap your app with StyledToast.

Simple global configuration, wrap you app with StyledToast.

StyledToast(
  locale: const Locale('en', 'US'),
  child: MaterialApp(
            title: appTitle,
            showPerformanceOverlay: showPerformance,
            home: LayoutBuilder(
              builder: (BuildContext context, BoxConstraints constraints) {
                return MyHomePage(
                  title: appTitle,
                  onSetting: onSettingCallback,
                );
              },
            ),
          ),
)

@JackJonson Thanks for the simple solution.
