I have array fetched from firestore database successfully, for which I am trying to build a list for array using ListView.builder
but not able to do so.
here is the array list I have
[{step: ffg}, {step: fgsgg}, {step: fgfda}]
code for list view builder
Expanded(
child: ListView.builder(
itemCount: widget.steps.length,
itemBuilder: (context, index) => Container(
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Text(
//"STEPS ${index + 1}",
"${widget.steps}",
],
),
),
),
),
Here is the screenshot of the result I am getting
I want the list of array fetched in a serialized manner index wise. How am I suppose to achive it? This is how I want the list to be displayed
You can do it like this using a Column
..
Column(
children: widget.steps.map((item){
return Text('${item['step']}');
}).toList(),
)
..or using a ListView.builder
like this..
ListView.builder(
itemCount: widget.steps.length,
itemBuilder: (BuildContext context, int index){
return Text('${widget.steps[index]['step']}');
},
)
You need to reference an index within the array in the builder. widget.steps
is using the default toString
method of List
to put convert it to a String
.
And if you want to not use the default toString
of Map
(which is what is contained at each List
reference), reference the Map
item you want to show as well.
Both reference operators for these object are []
Expanded(
child: ListView.builder(
itemCount: widget.steps.length,
itemBuilder: (context, index) => Container(
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Text(
"${widget.steps[index]['step']}",//Reference an index & key here. This is why index is provided as a parameter in this callback
],
),
),
),
),
Just use
Text( "${widget.steps[index]['step']}",)
From your response widget.steps
is a List of type Map so to get what's inside the list:
Try this: Text("${widget.steps[index][step]}")
