Datas from TextFormFields is null in Firebase database
I am having a hard time figuring this one out (im still new to flutter btw), I created a new screen with form that lets the user fill it out with information and after filling them out, there is a validator and onSaved: on EACH TextFormField() as of the moment, I just want the textform fields to have the datas saved to Firebase Database.
EDIT: I managed to make it work somehow using this code BUT the data Ive input in is nulled in Firebase database (second pic):
child: FlatButton(
color: Colors.blue,
child: Text("Confirm", style: TextStyle(color: Colors.white)),
onPressed: () async {
await db.collection("createdoffers").add(
{
'name': offerName,
'type': offerType,
'start': start,
'end': end,
}
);
},
),
Ive also watched some tutorial but Im having trouble making it work since its kind of a bit different to what Im trying to do (I guess its a beginners problem, Im new to programming and I fell in love with flutter lol)
Now on my Firebase console, I created a new collection with some new dummy data just to fill in (mind you, I still dont save INPUTS from the app, just created a collection and put in some dummy data)
The image of my firebase is below:
NULLED data
my code is below for the screen form that I am trying to save data from INPUTS in the TextFormField and saving it all to my database by clicking the FlatButton
My target for this is: 1. Save the data to firebase 2. Read that data and display it to a Container widget, I just want the C and R in CRUD for now

WHAT I TRIED SO FAR
child: FlatButton(

onPressed: () {
setState(() async{
await db.collection("createdoffers").add(
{
'name': offerName,
'type': offerType,
'start': start,
'end': end,
}
);
}
);
}
)

You're passing the value of the textformfield during onsaved. But you forgot to save the form. Add this _formKey.currentState.save();
child: FlatButton(
color: Colors.blue,
child: Text("Confirm", style: TextStyle(color: Colors.white)),
onPressed: () async {
_formKey.currentState.save();
await db.collection("createdoffers").add(
{
'name': offerName,
'type': offerType,
'start': start,
'end': end,
}
);
},
),

What Went Wrong
child: FlatButton(
color: Colors.blue,
child: Text("Confirm", style: TextStyle(color: Colors.white)),
onPressed: () async {
await db.collection("createdoffers").add(
{
'name': offerName, // This is null, try to change the way you save data via setState
'type': offerType,
'start': start,
'end': end,
}
);
},
),
What you can do
If you are continuing with this implementation, please do try TextEditingController.
// Declaration
TextEditingController _offerNameTextController = TextEditingController();
// Usage
TextFormField(
controller: _offerNameTextController,
...
)
// Retrieving data from the input field
FlatButton(
onPressed: () {
// Utilize the value (eg. on your Firebase saving method
print(_offerNameTextController.text);
}
)
