Removing a widget is easy, but what if you need it to disappear but still take up space? Use Opacity! Wrap a widget with Opacity, set it to zero, and you're set. Try AnimatedOpacity if you want to animate the change!!

So I am trying to make a contacts list, similar to what we have on a smart phones. I am at the stage where I have a list of contacts, but I am unable to click on a contacts name in that list, and it take me to the desired contact. I know it's a navigation problem, but I don't know how to fix it. Any help, would be great.​class ContactList extends StatelessWidget {
final List<Contact> _contacts;ContactList(this._contacts);@override
Widget build(BuildContext context) {
return new ListView.builder(
padding: new EdgeInsets.symmetric(vertical: 8.0),
itemBuilder: (context, index) {
return new _ContactListItem(_contacts[index]);
},
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => MyApp()),
);
},itemCount: _contacts.length,
);}
}

Reddit: How to implement a search bar without blocking users view
So at the moment I have a contacts list where I can view my contacts in a static list. I want to be able to click on the search bar, and instead of it dropping over the contacts, obscuring users view, the search will open up in a new blank page as the user types.

 class _ContactPage extends State<ContactsPage> { @override Widget build(BuildContext context) { return new MaterialApp( home: new Scaffold( appBar: new AppBar( title: widget.appBarTitle, actions: <Widget>[ new IconButton( icon: widget.actionIcon, onPressed: () { setState(() { if (widget.actionIcon.icon == Icons.search) { widget.actionIcon = new Icon(Icons.close); widget.appBarTitle = new TextField( style: new TextStyle( color: Colors.white, ), decoration: new InputDecoration( prefixIcon: new Icon(Icons.search, color: Colors.white), hintText: "Search...", hintStyle: new TextStyle(color: Colors.white)), onChanged: (value) { print(value); //filter your contact list based on value }, ); } else { widget.actionIcon = new Icon(Icons.search); //reset to initial state widget.appBarTitle = new Text("Contacts"); } }); }, ), ], ), body: new ContactList(kContacts)), ); } }
