EmergentToggle class

Switch with custom thumb (defined with list of ToggleElements)

does not save the state

• notifies a ValueChanged<int> : onChanged
• need a selectedIndex parameter oggle Expanded( child: EmergentToggle( height: 50, selectedIndex: _selectedIndex, displayForegroundOnlyIfSelected: true, children: ToggleElement( background: Center(child: Text("This week", style: TextStyle(fontWeight: FontWeight.w500),)), foreground: Center(child: Text("This week", style: TextStyle(fontWeight: FontWeight.w700),)), ), ToggleElement( background: Center(child: Text("This month", style: TextStyle(fontWeight: FontWeight.w500),)), foreground: Center(child: Text("This month", style: TextStyle(fontWeight: FontWeight.w700),)), ), ToggleElement( background: Center(child: Text("This year", style: TextStyle(fontWeight: FontWeight.w500),)), foreground: Center(child: Text("This year", style: TextStyle(fontWeight: FontWeight.w700),)), ) , thumb: Emergent( boxShape: EmergentBoxShape.roundRect(borderRadius: BorderRadius.all(Radius.circular(12))), ), onChanged: (value) { setState(() { _selectedIndex = value; print("_firstSelected: $_selectedIndex"); }); }, ), ),
