打開鍵盤時如何將所有內容向上推

Question

是否可以在打開鍵盤時將所有內容上推？ （不只是textField區域，整個頁面push up）

   showModalBottomSheet(
       context: context,
       builder: (BuildContext context) {
            return BottomSheet();
       },
   isScrollControlled: true);

底片 class

class BottomSheet extends StatefulWidget {
  @override
  _BottomSheetState createState() => _BottomSheetState();
}

class _BottomSheetState extends State<BottomSheet> {

  @override
  Widget build(BuildContext context) {
    return
      SingleChildScrollView(
        padding: EdgeInsets.only(
            bottom: MediaQuery.of(context).viewInsets.bottom),
            child: Container(
                child: Column(
                  children: <Widget>[...

我想喜歡這個俯卧撐，

但當前 output 是，

Answer 1

如果您使用堆棧，您可以簡單地為小部件提供MediaQuery.of(context).viewInsets.bottom的bottom position。

在您的情況下，將margin:設置為MediaQuery.of(context).viewInsets.bottom而不是填充。

Answer 2

只需將reverse=true放入SingleChildScrollView就足夠了。

Widget build(BuildContext context) {
  return Scaffold(
    body: SafeArea(
      child: SingleChildScrollView(
        reverse: true,
        child: Container(
          ........
          ........ 

Answer 3

將整個小部件包裝在一個容器中，並像這樣提供容器填充，它會起作用。

child: Container(
      padding: EdgeInsets.only(
        top: 25.0,
        bottom: MediaQuery.of(context).viewInsets.bottom,
        left: 25.0,
        right: 25.0,
      ),
      child: Form(
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.stretch,
          children: [
            TextFormField(
              decoration: InputDecoration(
                hintText: 'Email',
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(10.0),
                ),
              ),
              keyboardType: TextInputType.emailAddress,
              validator: (value) {
                return _isEmailValid(value);
              },
              textInputAction: TextInputAction.next,
              onSaved: (value) {},
              controller: _emailController,
            ),
            SizedBox(height: 10),
            TextFormField(
              obscureText: true,
              decoration: InputDecoration(
                hintText: 'Password',
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(10.0),
                ),
              ),
              keyboardType: TextInputType.emailAddress,
              validator: (value) {
                return _isEmailValid(value);
              },
              textInputAction: TextInputAction.done,
              onSaved: (value) {},
              controller: _passwordController,
            ),
            Row(
              mainAxisAlignment: MainAxisAlignment.end,
              children: [
                TextButton(
                  onPressed: () {},
                  child: const Text('Forgot Password'),
                ),
              ],
            ),
            ElevatedButton(
              style: ElevatedButton.styleFrom(
                side: const BorderSide(width: 1.3, color: Colors.white),
                shadowColor: Colors.white,
              ),
              onPressed: () {},
              child: const Text('Login'),
            ),
            TextButton(
              onPressed: () {},
              child: Text('Not have any Accoung? Sign Up'),
            ),
          ],
        ),
      ),
    ),

Answer 4

將 Scaffold 的resizeToAvoidBottomInset屬性設置為 true。

Answer 5

showModalBottomSheet(
      context: context,
      isScrollControlled: true,
      builder: (BuildContext context) {
        return Container(
          padding: EdgeInsets.only(
            bottom: MediaQuery.of(context).viewInsets.bottom,
          ),
          child: //your code
        );
      }
)

這對我有用。 也許嘗試將您的填充物移到容器內。
