ReadyForm #
widget that wrap flutter form to simplify working with it
Features #
[x] Validate children [x] Scroll to first invalid item if validation failed [x] Ability to add reveal effect [x] ProgressButton that work smoothly with it
usage #

return OnPostDataResult();
},
child: ListView(
children: [
TextFormField(),
TextFormField(),
TextFormField(),
TextFormField(),
ProgressButton(child: Text(TR.of(context).login)),
],
),
);
- as you can see when you press the progress button the form will be submitted after check validations
so what if you need to submit your form by your self or you don't want to use the ProgressButton
#
then you have to use
ReadyFormKey
final ReadyFormKey formKey=ReadyFormKey();
Widget build(BuildContext context) {
return ReadyForm(
onPostData: () async {
/// submit your data
return OnPostDataResult();
},
child: ListView(
children: [
TextFormField(),
TextFormField(),
TextFormField(),
TextFormField(),
ElevatedButton(
onPressed:(){
formKey.onSubmit();
},
child: Text(TR.of(context).login),
),
],
),
);
}
you can also use
ReadyForm.of(context)
usage #
return ReadyForm(
onPostData: () async {
/// submit your data
return OnPostDataResult();
},
child: ListView(
children: [
TextFormField(),
TextFormField(),
TextFormField(),
TextFormField(),
Builder(builder: (context) {
// the context of the builder can now access the parent form
return ElevatedButton(
onPressed: () {
ReadyForm.of(context)!.onSubmit();
},
child: Text(TR.of(context).login),
);
}),
],
),
);
global configuration #
you can also configure all forms in your app using ReadyFormConfig
KeyboardActions #
there is a widget called KeyboardActions
witch add three buttons on the top of keyboard when it was opened
next
prev
hide keyboard
, these icons are useful in ios as the ios keyboard does not contains a button to hide it
- ReadyForm by default use this widget but you can disable it globally or in single form
- You can also use this widget without the form its up to you
- to make sure this widget works perfect you have to pass your preferred
FocusTraversalPolicy
i suggestOrderedTraversalPolicy
and wrap each field with FocusTraversalOrder
FocusTraversalOrder(
order: NumericFocusOrder(1),
child: ...
),
validation mode #
every form can has the validation mode instead of flutter [AutoValidateMode] enum
you can use [FormAutoValidateMode] which contains onSubmit
- it can be also configured globally
scrolling to invalid field visibility #
without any configuration this package scrolls to the first invalid field when [onSubmit]
but some time you want to override this behavior
EnsureContextVisible(
after:(context) async{
/// this will be called after the default behaviour
}
before:(context) async{
/// this will be called after the default behaviour
}
);
EnsureContextVisible.override(
ensureVisible:(context) async{
/// this will override the default behaviour
}
);
- if your wrap a single field
Submit errors #
some time you want to show custom errors after calling onPostData #
as you ca see
onPostData
can returnOnPostDataResult
which may contains error map the errors returned fromonPostData
not affect the cycle but they ca be shown by user in two ways
- the first one is
ReadyFormErrorMessages
this widget can show the submit error messages and you may use the custom builder to make your own ui ,
if you used the builder you also have an access to the invalid fields
return ReadyForm(
onPostData: () async {
/// submit your data
return OnPostDataResult({
"email":"The email already exist"
});
},
child: ListView(
children: [
ReadyFormErrorMessages(),
TextFormField(),
TextFormField(),
TextFormField(),
TextFormField(),
ProgressButton(child: Text(TR.of(context).login)),
],
),
);
- the second one is
SubmitErrorMessageFor
which show an error for specified key
return ReadyForm(
onPostData: () async {
/// submit your data
return OnPostDataResult({
"email":"The email already exist"
});
},
child: ListView(
children: [
TextFormField(),
SubmitErrorMessageFor(messageFor:'email')
TextFormField(),
TextFormField(),
TextFormField(),
ProgressButton(child: Text(TR.of(context).login)),
],
),
);
/// or if you need to show it with other errors of the field
return ReadyForm(
onPostData: () async {
return OnPostDataResult({ "email":"The email already exist" });
},
child: ListView(
children: [
SubmitErrorMessageFor(
messageFor: 'email',
builder: (form, error) {
return TextFormField(
decoration: InputDecoration(
errorText: error,
hintText: "Email",
),
);
},
),
TextFormField(),
TextFormField(),
TextFormField(),
ProgressButton(child: Text(TR.of(context).login)),
],
),
);
