Unexpected margin inside Flutter Column widget

i'm writing a code inside a column, but i have an unexpecting size. I think it's a margin, but i don't know where it was .. Does someones had this thing ?

Column(
      children: [
        Text("test"),
        // Here some margin, why ?
        Container(
          height: 200,
          child: ListView.builder(
            shrinkWrap: true,
            itemCount: answers.length,
            itemBuilder: (BuildContext context, int index) {
              return Text(answers[index]);
            }
          ),
        )
      ],
    );

I tried to put SizedBox instead of my Container but not work. Maybe it's normal ?
I tried to remove SizedBox or Container, to get only my ListView, but this blank is always here.

Here is Flutter Inspector :
The 20 height with green border is the Text "test" before the List enter image description here

Thanks !

Solution

  • It might the default padding of ListView. You could try

    ListView.builder(
  padding: EdgeInsets.zero,
  itemBuilder: (BuildContext context, int index) {
    return Text("answers[$index]");
  }),
)
