Constructors
Properties
- canNext → bool
-
Returns True if the following reads are possible
no setter
- disposed → bool
-
True if the model is Disposed.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- isEmpty → bool
-
Return
true
if data is empty.no setter - isNotEmpty → bool
-
Return
true
if data is not empty.no setter - loaded → bool
-
It becomes
true
afterloadOnce
is executed.no setter -
loading
→ Future<
void> ? -
Returns itself after the load finishes.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
saving
→ Future<
void> ? -
Returns itself after the save/delete finishes.
no setterinherited
Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
append(
String uid, {T? data}) → Future< void> -
Add a new document to the current collection based on
uid
. -
create(
[String? id]) → T - Create a new document.
-
delete(
bool test(T value)) → Future< void> -
Remove elements in the collection that are
true
intest
. -
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener and removeListener will throw after the object is
disposed).
inherited
-
fetch(
[bool listen = true]) → Future< void> - Provides the best data acquisition method to implement during screen build.
-
initState(
) → void -
The method to be executed when initialization is performed.
inherited
-
next(
) → Future< void> - Load the data on the next page.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
reload(
) → Future< void> - Reload data and updates the data in the model.
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
save(
) → Future< void> - Data stored in the model is stored in a database external to the app that is tied to the model.
-
toString(
) → String -
A string representation of this object.
inherited
-
transaction(
[String? linkedCollectionPath]) → CollectionTransactionBuilder - Generate a Transaction for this collection.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
