CodePudding user response：

Just wrap your code in SingleChildScrollView like below

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      child: Column(
        children: [
          // your rest code here...
        ],
      ),
    );
  }

CodePudding user response：

You can wrap your code in ListView or SingleChildScrollView instead of the column :

  @override
  Widget build(BuildContext context) {
    return ListView(
        children: [
          // your code
        ],
    );
  }
