Minimal code example

Code sample

FormBuilderFieldDecoration<ItemEntity>(
  name: fieldName,
  initialValue: initialValue,
  decoration: InputDecoration.collapsed(hintText: null),
  autovalidateMode: autovalidateMode,
  validator: FormBuilderValidators.compose([
    if (isRequired) FormBuilderValidators.required(),
    ...?validators,
  ]),
  builder: (state) {
    // this should not be needed if `initialValue` is set to `value`
    if (state.value == null && initialValue != null && state.mounted) {
      // waiting build finish then set initial value
      Future.microtask(() => state.didChange(initialValue));
    }

    return Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Text(
          state.value?.name ?? 'Choose_'.trlC(context),
          style: AppTextStyle.textM.setColor(
            AppColors.neutral.shade70,
          ),
        if (state.hasError)
          Text(
            state.errorText ?? '',
            style: AppTextStyle.formError,
          ).padding(top: 8),
      ],
    );
  },
);

Current Behavior

I need to set the state.value to initialValue manually and the code feels quite "hacky". Check example above.

Expected Behavior

On first render the state.value should not be null.

Steps To Reproduce

Just render the widget
