Answer 1

Here is what the error means, you made a CupertinoNavigationBar and are passing into it an actionsForegroundColor, but doing that is not allowed as of version 1.22.

You can read more about it on flutter 1.22 changes

the new way to pass the equivalent parameter is by adding a CupertinoTheme somewhere above your CupertinoNavigationBar (I believe CupertinoApp does this automatically if you pass the theme parameter?) and passing a Cupertino theme data object with the primary color value.

CupertinoTheme(
  data: CupertinoThemeData(
    primaryColor: data?.actionsForegroundColor,
  ),
  child: CupertinoNavigationBar(),
);

or on CupertinoApp

CupertinoApp(
  theme: CupertinoThemeData(
    primaryColor: data?.actionsForegroundColor,
  ),
  home: ...
);
