Steps to Remove TextField Underline/Border in Flutter

To remove TextField underline/border in Flutter, you can simply set the border property to InputBorder.none. This will remove the underline for all states such as Focused, Enabled, Error, Disabled.

Here are the steps:

Step1: Inside the TextField widget, make sure you have already added the decoration property with InputDecoration assigned.

Step 2: Inside the InputDecoration, add the border property and set it to InputBorder.none.

Step 3: Run the app.

Code Example:

TextField(
  decoration: InputDecoration(
    labelText: 'Enter Name',
    border: InputBorder.none,
  ),
)

Output:

remove textfield underline/border in for all states

  • Run the app.

Code Example:

  • Run the app.

Code Example:

  enabled: false,
  decoration: InputDecoration(
    labelText: 'David Jhon',
    disabledBorder: InputBorder.none,
  ),
)

To hide the border when TextField is having an error:

  • Inside the InputDecoration, add the errorBorder property and set it to InputBorder.none.
  • Run the app.

  decoration: InputDecoration(
    labelText: 'Enter Name',
    errorBorder: InputBorder.none,
  ),
)
