About a couple of days into flutter, but I can't figure how to add a border onTap to a Container that's wrapped in InkWell that is pageController (there are few in a row). I want my Container to have white border when tapped/selected, but for the love of god can't figure how.
Would appreciate any help/explanation, so I can learn from this.
Like on image below, when I tap on either of those the selected item has border around it
White Border upon onTap

CodePudding user response：
You can define two veriable bool isFirtButton = false and bool isSecondButton = false
and set border based on condition: First button border border:isFirtButton ? Border.all(color: Colors.white) : null), second button border border:isSecondButton ? Border.all(color: Colors.white) : null

Try this code below as reference you can customize as per your need :
create a List of bool like this :
List<bool> list = [false, false];
and paste this to your code
Row(
children: [
Expanded(
child: InkWell(
onTap: (){
setState(() {
list[0] = true;
list[1] = false;
});
},
child: Card(
color: list[0] ? Colors.blue : null,
child: Text("1st Container"),
),
),
),
Expanded(
child: InkWell(
onTap: (){
setState(() {
list[1] = true;
list[0] = false;
});
},
child: Card(
color: list[1] ? Colors.blue : null,
child: Text("2nd Container"),
),
),
),
],
)
CodePudding user response：
A simple way of doing it, using a bool to hold the state of click event.
bool enableBorder = false; // on state class
///... on inkWell
onTap: () => setState(() => enableBorder = !enableBorder)
For your case, just use
border: enableBorder ? Border.all(color: Colors.white) : null,
Update for List
List<int> selectionItems = [];
///
borderRadius:
selectionItems.contains(0) ? BorderRadius.circular(28) : null,
onTap: () => setState(() {
selectionItems.contains(0)
? selectionItems.remove(0)
: selectionItems.add(0);
}),
and use
border: selectionItems.contains(0)
? Border.all(color: Colors.white)
: null,
