我如何改变文字输入动作按钮(返回/输入键)的键盘在颤动？

One angle ... I have not explored all the "keyboardType" options within the TextField (optional parameter of TextInputType).

But there are some obvious different keyboards for 'emailAddress' and 'datetime' and 'phone' - one of those options may emit the keyboard that you are looking for ...

This is currently not possible. Although you can edit flutter sources to make it possible quite easily.

The following edits are :

flutter/lib/src/widgets/editable_text.dart

Change _openInputConnection line ~430 to

void _openInputConnection() {
if (!_hasInputConnection) {
final TextEditingValue localValue = _value;
_lastKnownRemoteTextEditingValue = localValue;
_textInputConnection = TextInput.attach(this,
new TextInputConfiguration(
inputType: widget.keyboardType,
obscureText: widget.obscureText,
autocorrect: widget.autocorrect,
inputAction: widget.keyboardType == TextInputType.multiline
? TextInputAction.newline
: TextInputAction.done
)
)..setEditingState(localValue);
}
_textInputConnection.show();
}

In the same file, also declare a new field on EditableText class (not the state one) ~line 280

final TextInputAction textInputAction;

And assign it in EditableText constructor above line 164

this.textInputAction,

flutter/lib/src/material/text_field.dart

Same story. Add a new field, but to TextField instead :

final TextInputAction textInputAction;

and add the following to it's constructor :

this.textInputAction,

Finally, pass that new field as parameter to EditableText line 479 :

    textInputAction: widget.textInputAction,

Done.

You can now inside your app specify a custom TextInputAction. This won't break existing TextField. It just adds the ability to override the default behavior.

new TextField(
keyboardType: TextInputType.text,
textInputAction: TextInputAction.newline,
),

The input action for a TextField (or TextFormField) can be specified like this (here, the Go button):

TextField(
textInputAction: TextInputAction.go
...
)

List of all available input actions.

This is how you can use textInputAction:

TextField(
textInputAction: TextInputAction.search,
onSubmitted: (value) {
print("search");
},
decoration: InputDecoration(
border: InputBorder.none,
prefixIcon: Icon(Icons.search),
hintText: 'Search ',
contentPadding: EdgeInsets.fromLTRB(20.0, 15.0, 20.0, 15.0),
),
);

basically we are use two types of text input fields, TextField and TextFormField,

so,

for TextField,

TextField(
textInputAction: TextInputAction.go
.......
)

for TextFormField,

TextFormField(
textInputAction: TextInputAction.go,
........
)

both have textInputAction property, we can use this

Here is how to add the action button and also listen to onTap

For TextField

TextField(
textInputAction: TextInputAction.go,
onSubmitted: (value) {
print("Go button is clicked");
},
decoration: InputDecoration(
border: InputBorder.none,
contentPadding: EdgeInsets.fromLTRB(20.0, 15.0, 20.0, 15.0),
),
);

For TextFormField

TextFormField(
textInputAction: TextInputAction.go,
onFieldSubmitted: (value) {
print("Go button is clicked");
},
decoration: const InputDecoration(
hintText: "Type your search here",
hintStyle: TextStyle(color: Colors.black26),
filled: true,
fillColor: Colors.white,
border: OutlineInputBorder(
borderSide: BorderSide.none,
borderRadius: BorderRadius.all(Radius.circular(40.0)),
),
contentPadding:
EdgeInsets.symmetric(horizontal: 20.0, vertical: 16.0)),
)

Anyone looking for UIReturnKeyDone is like this:

TextField(
textInputAction: TextInputAction.done
...
)
