Explanation:

From now-onwards I will explain only main things because when I place a lot of code here you will be confused .Thereby you can see all source code in my Github (I will place a link here).

  • To copy the exact code to start building click here.
  •  theme: defaultTargetPlatform == TargetPlatform.iOS ? ThemeData.dark(): ThemeData.light() , here based on the OS we are defining the theme.Otherwise you can define by using ThemeData property.
  • shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10.0),), : If you want a shape for the Appbar or someother widgets use shape property.
  • Define a Global Key which is of FormState and Controller for controlling the text in TextFormField.
  • If you want to validate your Form use Validator property.
  • validator: (val) { if (val.isEmpty) { return "Please Enter A Task"; } return null; },
  • onSaved: (val) { _controller.text = val; },
  • When ADD button is pressed we have to check whether the TextFormField is empty or not here we can solve it by using validator and by using a formKey.
  • _validateForm() { if (_key.currentState.validate()) { setState(() {
    • _todos.add(_controller.text); }); _controller.clear(); Navigator.of(context).pop(); } }.
