flutter 开发中遇到的问题

1.An InputDecorator, which is typically created by a TextField, cannot have an unbounded width.

TextField需要指定边界，例如外层包一个SizedBox，或者添加Expanded

2.A RenderFlex overflowed by 99887 pixels on the bottom.

界面布局超出边界

3.type 'Future<dynamic>' is not a subtype of type 'String'

数据类型不匹配

4.Invalid argument(s): No host specified in URI file:///

非法参数

5.Column's children must not contain any null values, but a null value was found at index 0

column的子项必须不能有空

6.A SingleTickerProviderStateMixin can only be used as a TickerProvider once

将SingleTickerProviderStateMixin改成TickerProviderStateMixin

7.Horizontal viewport was given unbounded height.

高度未指定边界，或者高度计算有问题

8.Navigator.pop(context)黑屏问题

BuildContext错误，Scaffold的BuildContext可能是上一个页面的context

9. This package referenced a Flutter repository via the .packages file that is no longer available.

可能由于sdk未配置，导致无法识别文件

10.No Directionality widget found.

text设置属性textDirection
