Posted at 2025-10-16

やりたいこと

TextFieldの下線がダサくて邪魔だから消したい。

edit_title_view.dart

TextFormField(
    controller: _titleController,
    onFieldSubmitted: (value){},
)

解決策

InputDecorationのborderをnoneにすることで枠線を消すことが出来る

edit_title_view.dart

TextFormField(
    controller: _titleController,
    decoration: InputDecoration(
      border: InputBorder.none
    ),
    onFieldSubmitted: (value){},
)
