validate method
Validates all FormCraftTextField widgets and returns true if all are valid.
Iterates through each field, validates its content, and returns a boolean indicating overall validity.
Implementation
bool validate() {
// List to store the validation results for each field
var validate = <bool>[];
_globalKeys.forEach((key, value) {
// Validate the current field and add the result to the list
final isValid = _globalKeys[key]!.currentState!.validate();
validate.add(isValid);
});
// Return true if all fields are valid, false otherwise
return validate.every((element) => element);
}
