I have a list of single word in a page, I want to know how to center these words and move the extended word in a row to next line, as shown in Image 2

This is Image 1, which I use gridview, but I cannot center the words, and the number of the word in each row is fix.


Below is Image 2, this is the result I want to get. Instead of using GridView widget, is there any other option to do?

Below are the code:

Expanded(
child: FutureBuilder<WordModel>(
  future: alphabetsList(),
  builder: (context, snapshot) {
    if (snapshot.hasData) {
      return ListView.builder(
          itemCount: snapshot.data.words.length,
          itemBuilder: (context, index) => Wrap(
            alignment: WrapAlignment.center,
            children: [
              Padding(
                  padding: EdgeInsets.all(18.0),
                  child: Text(
                    snapshot.data.words[index].name.toString(),
                ),
              )
            ],
          )
      );
    } 
  },
),

You can use a Wrap for that. For example:

import 'package:flutter/material.dart';

void main() {
  final list = [
    "Apple",
    "Balloon",
    "Cake",
    "Dog",
    "Egg",
    "Flamingo",
    "Grape",
    "House",
    "Ice-Cream",
    "Jellyfish",
    "Kite",
    "Lemon",
    "Mouse",
    "Nose"
  ];

  runApp(MaterialApp(
      home: Scaffold(
    body: Wrap(alignment: WrapAlignment.center, children: [
      for (String s in list)
        Padding(
          padding: const EdgeInsets.all(18.0),
          child: Text(
            s,
            style: const TextStyle(fontSize: 40),
          ),
        )
    ]),
  )));
}

Output:

EDIT:

with your code it could be something like this:

if (snapshot.hasData) {
  return Wrap(alignment: WrapAlignment.center, children: [
  for (final word in snapshot.data.words)
    Padding(
      padding: const EdgeInsets.all(18.0),
      child: Text(
        word.name.toString()
      ),
    )
   ]);
}

try the Wrap widget: Like this

and if you want to implement this with listView: check this
