在 Flutter 中创建按钮变量的问题

Question

I am currently using flutter for an android app and I am using the "Routegenerator.dart" method for navigating . In this project, a certain button gets repeated multiple times and always leads to the same page. I want to create a variable of this button to clean the code a bit and avoid myself useless repetitions. The issue here is that I need to put the variable after the class with the scaffold, and this causes the Navigator.of(context).pushNamed() to give me an error in the (context). How to solve this issue please?

Answer 1

you can call TextButtonWidget anywhere in your screen like this:

 TextButtonWidget(
         onTap: (){
           Navigator.of(context).pushNamed('anyScreen');
      },),

Import this widget

   import 'package:flutter/material.dart';

class TextButtonWidget extends StatelessWidget {
  const TextButtonWidget({
    Key? key,
    required this.onTap,
  }) : super(key: key);
  final VoidCallback onTap;

  @override
  Widget build(BuildContext context) {
    ThemeData _theme = Theme.of(context);
    return Material(
      color: Colors.transparent,
      child: InkWell(
        onTap: onTap,
        child: Container(
            padding: const EdgeInsets.all(8.0),
            child: const Text('Choose me')),
      ),
    );
  }
}
