Can't encode default theme data.

[bimsina]

 var encodedTheme = ThemeEncoder.encodeThemeData(ThemeData.light());
 print(encodedTheme);

The above code produces the following exception:

'package:json_theme/src/codec/theme_encoder.dart': Failed assertion: line 3546 pos 12: 'value == null ||
        value is CircleBorder ||
        value is ContinuousRectangleBorder ||
        value is RoundedRectangleBorder': is not true.

Just to confirm, can you add in the information from flutter doctor?

Also, it isn't just with the default themes, the following code also throws the same exception

Map<String, dynamic> themeJson = {};
var theme = ThemeDecoder.decodeThemeData(themeJson);
print(theme);
var encodedTheme = ThemeEncoder.encodeThemeData(theme);
print(encodedTheme);

It successfully decodes the json to a theme, but throws exception on encoding the same theme.

Thanks for the info. I just published a fix with 1.4.2. Closing this, please feel free to add a new issue if you encounter any more problems.
