I have a basic login page that consists of an 'email', 'password' and a 'SwitchListTile' (Switch) that users will select to confirm reading of legal documents. On 'Login', I would like the 'Text' to show. Default is invisible.

I implemented the visibility of the Text using the 'Visibility' class. Now I would like to make it visible using an 'if-else' check.

 SwitchListTile(
 value: _acceptTerms,
 onChanged: (bool value) 
 setState(() 
 _acceptTerms = value;
 );
 ,
 title: Text('Accept T&Cs'),
 ),
 SizedBox(height: 5.0),
 Visibility(
 visible: false,
 child: Text(
 'Please accept Terms & Conditions!',
 style: TextStyle(color: Colors.red),
 )),
 SizedBox(
 height: 10.0,
 ),
 RaisedButton(
 color: Theme.of(context).primaryColor,
 textColor: Colors.white,
 child: Text('LOGIN'),
 onPressed: () 
 print(_emailValue);
 print(_passwordValue);
 if(_acceptTerms) 
 Navigator.pushReplacementNamed(context, '/products');
 else 
 //code to make invisible text visible
 
 ,
 ),

I'm still new to Flutter and Dart development. Thanks.

The only way to do this in flutter is to create a variable

var tcVisibility = false

set the visibility of the text box to the variable

Visibility(
 visible: tcVisibility,
 child: Text(
 'Please accept Terms & Conditions!',
 style: TextStyle(color: Colors.red),
)),

then in the code update the variable

if(_acceptTerms) 
 Navigator.pushReplacementNamed(context, '/products');
 else 
 setState(() 
 tcVisibility = true;
 );

  Instead of tcVisibility = false;, it should be tcVisibility = true; in else clause.
