Flutter 中 TextField 的默认填充是什么？

Question

Dear Flutter Developers,

I want to know the default value used in contentPadding property inside InputDecoration() for TextField or TextFormField in Flutter.

Answer 1

According to the Flutter documentation here: Flutter > material > InputDecoration > contentPadding

By default the contentPadding reflects [isDense] and the type of the [border].

If [isCollapsed] is true then contentPadding is [EdgeInsets.zero].

If isOutline property of [border] is false and if [filled] is true then contentPadding is EdgeInsets.fromLTRB(12, 8, 12, 8) when [isDense] is true and EdgeInsets.fromLTRB(12, 12, 12, 12) when [isDense] is false.

If isOutline property of [border] is false and if [filled] is false then contentPadding is EdgeInsets.fromLTRB(0, 8, 0, 8) when [isDense] is true and EdgeInsets.fromLTRB(0, 12, 0, 12) when [isDense] is false.

If isOutline property of [border] is true then contentPadding is EdgeInsets.fromLTRB(12, 20, 12, 12) when [isDense] is true and EdgeInsets.fromLTRB(12, 24, 12, 16) when [isDense] is false.

NOTE: The value of isOutline property is true for OutlineInputBorder() and is false for UnderlineInputBorder()
