chatGPT にプログラミングさせてみた。
そのままでは動作しなかったが、少しの修正をするだけで、動作した。恐るべし！

0; col < 3; col++)
GestureDetector(

width: 80,
height: 80,
decoration: BoxDecoration(

Column(
children: [
SizedBox(height: 20),
Text(
_winner == 'Tie'
? 'It's a tie!'
: 'Player ${_winner == 'X' ? '1' : '2'} wins!',
style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold),
),
SizedBox(height: 20),
ElevatedButton(
onPressed: _resetGame,
child: Text('Play Again'),
),
],
),
],
),
),
);
}
}
This code is similar to the previous code, with a few differences. First, we no longer need to import `material.dart` explicitly because it is included in the Flutter SDK by default in Flutter 3. Second, we no longer need to add the `late` keyword to the `_board`, `_player1Turn`, and `_winner` variables because null safety is now enabled by default in Flutter 3. Finally, we use a `Container` instead of a `Stack` to show the X's and O's in the cells because it is more efficient.
I hope this helps! Let me know if you have any questions.
