I am getting an error while trying to compile my code could anyone help me fix it? I am trying to create a list of buttons that will navigate to another screen. It was previously a expansion tile and I am trying to switch it to a list tile.
return ListTile(
title: Text(StudyViewModel.studies[index].name,
style: TextStyle(fontSize: 18.0)),
children: <Widget>[
ListView.builder(
shrinkWrap: true,
physics: ClampingScrollPhysics(),
itemCount: StudyViewModel.studies[index].tasks.length,
itemBuilder: (context, int taskIndex) {
return ListTile(
title: Text(StudyViewModel.studies[index].tasks[taskIndex].name),
contentPadding: EdgeInsets.symmetric(horizontal: 32.0),
subtitle: Text(
StudyViewModel.studies[index].tasks[taskIndex].elapsedTime),
);
},
),
Based off of responses, the goal of this code is to create a list of buttons that have previously been defined in a template. These buttons will be used in a time study app. I would like to be able to upload the activities into a new page. Originally, the code was written as an expansiontile, but I am trying to change it to a listtile. The error we are encountering is:
lib/pages/home_page.dart:107:7: Error: No named parameter with the name 'children'. children: [ ^^^^^^^^ ../../lib/flutter/packages/flutter/lib/src/material/list_tile.dart:762:9: Context: Found this candidate, but the arguments don't match. const ListTile({ ^^^^^^^^ Failed to compile application.
CodePudding user response:
The ListTile widget doesn't contain a parameter named children. In your code you're setting a parameter 'children' which is invalid.
This might help:
return ListView(
children: <Widget>[
Text(StudyViewModel.studies[index].name,
style: TextStyle(fontSize: 18.0),
),
ListView.builder(
shrinkWrap: true,
primary: false,
itemCount: StudyViewModel.studies[index].tasks.length,
itemBuilder: (context, int taskIndex) {
return ListTile(
title: Text(StudyViewModel.studies[index].tasks[taskIndex].name),
contentPadding: EdgeInsets.symmetric(horizontal: 32.0),
subtitle: Text(StudyViewModel.studies[index].tasks[taskIndex].elapsedTime),
);
},
),
