final
- autosave → bool
-
Automatically saves a changed value.
If autovalidate is
true
then a changed value will only be saved if there is no validation failure. Also invokes method onSaved. Default istrue

-
Controls how one widget replaces another widget in the tree. [...]
final, inherited
-
map
→ Map<
String, dynamic> -
map is used together with path to provide the initial value from

-
onSaved
→ ValueSetter<
T> -
An optional method to call with the final value when the form is saved
through InputFormState.save().
final, inherited
- path → String
-
The path to the fields value in map.
If the form is nested then path elements must be dot separated.
