Could not build the precompiled application for the device.Error (Xcode):

1、报错原因如下:

Could not build the precompiled application for the device.
Error (Xcode): ../../.pub-cache/hosted/pub.flutter-io.cn/universal_html-2.2.2/lib/src/html/dom/element_subclasses.dart:2752:30: Error: The argument type 'String?' can't be assigned to the parameter type 'Object' because 'String?' is nullable and 'Object' isn't.

2、解决方案 在pubspec.yaml添加

universal_html: ^2.2.4

It seems like you're encountering an issue while trying to install a project that has a dependency on scipy. The error message indicates that the wheel for scipy could not be built. This error often occurs when there are missing or incompatible dependencies required for building the scipy wheel. To resolve this issue, you can try the following steps: 1. Make sure you have the necessary build tools installed on your system. For example, on a Linux system, you might need to install packages like gcc, g++, and Fortran compilers. 2. Ensure that you have all the required dependencies for scipy installed. These dependencies can vary depending on your operating system. You can refer to the scipy documentation for a list of required dependencies. 3. Try upgrading pip and setuptools to their latest versions by running the following commands: ``` pip install --upgrade pip pip install --upgrade setuptools ``` 4. If you are using a virtual environment, deactivate and reactivate it. This can help ensure that the environment is using the updated versions of pip and setuptools. 5. If the issue persists, you can try installing scipy using precompiled binary wheels instead of building from source. You can find precompiled scipy wheels for different platforms on the Python Package Index (PyPI). Download the appropriate wheel for your system and install it using pip. If none of these solutions work, please provide more details about your system, the exact error message you're seeing, and any other relevant information.
