How to change obscure character of text field in flutter?

Question

I want to use '*' instead of '•' in text field.

TextField(
  focusNode: _passwordFocusNode,
  controller: _passwordController,
  obscureText: true,
);

Answer 1

Now flutter does support this feature for a textfield by setting the obscuringCharacter property, it takes a string strict to 1 character and the obscureText property should be true in order to take this effect

TextField(
  obscuringCharacter: '&', // defaults to *
  obscureText: true,
)

Answer 2

Flutter currently does not support this feature. Obscuring text is controlled by the property obscureText which takes a boolean expression. As you can see in the docs

When this is set to true, all the characters in the text field are replaced by U+2022 BULLET characters (•).
