revalidate method

void revalidate(BuildContext context, FormValidationMode state)

Revalidates all form fields with validators.

Runs validation on all registered fields and updates their validation states. Supports both synchronous and asynchronous validators.

Parameters:

• context (BuildContext, required): The build context.
• state (FormValidationMode, required): Validation mode to use.

Implementation

void revalidate(BuildContext context, FormValidationMode state) {
  bool changed = false;
  for (var entry in _attachedInputs.entries) {
    var key = entry.key;
    var value = entry.value;
    if (value.validator != null) {
      var future = value.validator!.validate(context, value.value, state);
      if (_validity[key]?.result != future) {
        if (future is Future<ValidationResult?>) {
          _validity[key] = _ValidatorResultStash(future, state);
          future.then((value) {
            if (_validity[key]?.result == future) {
              _validity[key] =
                  _ValidatorResultStash(value?.attach(key), state);
              WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
                if (_disposed) {
                  return;
                }
                notifyListeners();
              });
            }
          });
        } else {
          _validity[key] = _ValidatorResultStash(future, state);
        }
        changed = true;
      }
    }
  }
  if (changed) {
    WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
      if (_disposed) {
        return;
      }
      notifyListeners();
    });
  }
