How to remove/adjust the space between RadioListTiles inside ListView?

Question

I have created a ListView of RadioListTiles, however there is too much space between the RadioListTiles. How can I remove them? There is no property of padding inside its constructor.

This is my code

 @override Widget build(BuildContext context) {

    Column taskView = Column(

      children: <Widget>[  
        ...,
        Expanded(
          child: ListView.builder(
            padding: EdgeInsets.all(0.0),
            itemCount: tasks.length,
            itemBuilder: (context, index) {
              return RadioListTile<String>(
                title:  Text(tasks[index]),
                value: tasks[index],
                groupValue: selectedRadio,
                onChanged: (val){
                    setSelectedRadio(val);
                }
              );
            },
          ),
        ),
      ],
    );
    return Scaffold(
      body: taskView,
    );
  }

Answer 1

Wrap title with Align widget like this

RadioListTile<String>(
      title: Align(
        child: Text(tasks[index]),
        alignment: Alignment(-1.1, 0),
      ),
      value: tasks[index],
      groupValue: selectedRadio,
      onChanged: (val) {
        setSelectedRadio(val);
      },
    );

Answer 2

you can try padding control to wrap your text or RadioListFile.. try this way..

return Padding(
        padding: const EdgeInsets.all(8.0),
        child: RadioListTile<String>(
            title:  Padding(
              padding: const EdgeInsets.all(8.0),
              child: Text(tasks[index]),
            ),
            value: tasks[index],
            groupValue: selectedRadio,
            onChanged: (val){
              setSelectedRadio(val);
            }
        ),
      );

Answer 3

if you want to remove space horizontally then use

       contentPadding: EdgeInsets.all(4.0),  

inside RadioListTile which remove space bydefault is 16.0.

Answer 4

To remove horizontal padding use this property:

   contentPadding: EdgeInsets.zero,

For vertical padding all I could do to decrease padding a little bit is:

   dense: true,
