Question

Answer 1

In your ThemeData , you have the option for a TextSelectionTheme (recent versions have migrated to this, if you are using an older version the properties are individual properties on ThemeData . Here are the docs for it and an example from the migration docs :

ThemeData(
  textSelectionTheme: TextSelectionThemeData(
    cursorColor: Colors.red,
    selectionColor: Colors.green,
    selectionHandleColor: Colors.blue,
  )
)

EDIT: If you just want to change a single widget's theme, you can wrap your build function with the Theme widget like this:

  Widget build(BuildContext context) {
    return Theme(
        child: MyWidget(),
        data: ThemeData(
            textSelectionTheme: TextSelectionThemeData(
          cursorColor: Colors.red,
          selectionColor: Colors.green,
          selectionHandleColor: Colors.blue,
        )));
  }
