Change fill color of InputDecorationTheme on error-CodePudding

I want to change fill color of InputFormField when error occures. But in theme I didn't find property like errorFillColor. So how can I change of InputFormField when state of field changes? Here is my code from theme:

 inputDecorationTheme: InputDecorationTheme(
      contentPadding: const EdgeInsets.all(AppDimension.paddingLarge),
      filled: true,
      iconColor: Colors.black,
      fillColor: AppColor.greyColor.withOpacity(0.7),
      border: OutlineInputBorder(
          borderRadius: BorderRadius.circular(AppDimension.radiusLarge),
          borderSide: BorderSide.none),
      disabledBorder: OutlineInputBorder(
          borderRadius: BorderRadius.circular(AppDimension.radiusLarge),
          borderSide: BorderSide.none),
      enabledBorder: OutlineInputBorder(
          borderRadius: BorderRadius.circular(AppDimension.radiusLarge),
          borderSide: BorderSide.none),
      focusedErrorBorder: OutlineInputBorder(
          borderRadius: BorderRadius.circular(AppDimension.radiusLarge),
          borderSide: BorderSide.none),
      errorBorder: OutlineInputBorder(
          borderRadius: BorderRadius.circular(AppDimension.radiusLarge),
          borderSide: BorderSide.none),
    ),

And here is what I need:

Moreover I can't find one rrorIconColor to change color of icon of field.

Thanks!)

CodePudding user response：

Here as an example for fillColor. Meaning you should follow the same principal for iconColor.

fillColor: MaterialStateColor.resolveWith((Set<MaterialState> states) {
        if (states.contains(MaterialState.focused)) {
          return Colors.green;
        }
        if (states.contains(MaterialState.error)) {
          return Colors.red;
        }
        return Colors.black;
      }),
