我有这个项目，当我没有添加chatview: ^1.2.0+1时工作正常。现在将其添加为依赖项后，出现以下错误
\nBecause chatview >=1.0.0 depends on intl ^0.18.0 and mobile_app depends on intl ^0.17.0, chatview >=1.0.0 is forbidden.\nSo, because mobile_app depends on chatview ^1.2.0+1, version solving failed.\npub get failed\ncommand: "/Users/samuel/flutter/bin/cache/dart-sdk/bin/dart __deprecated_pub --directory . get --example"\npub env: {\n "FLUTTER_ROOT": "/Users/samuel/flutter",\n "PUB_ENVIRONMENT": "vscode.dart-code:flutter_cli:get",\n "PUB_CACHE": "/Users/samuel/.pub-cache",\n}\nexit code: 1\n现在我更改了我期望工作正常的intl软件包版本，但我还收到了另一个错误intl ^0.18.0
Because mobile_app depends on flutter_localizations from sdk which depends on intl 0.17.0, intl 0.17.0 is required.\nSo, because mobile_app depends on intl ^0.18.0, version solving …我已经经历这个错误很长时间了。我已尽力按照网上的解决方案来解决该问题，但似乎没有任何效果。下面是堆栈跟踪
Unable to install /Users/samuel/Desktop/Projects/flutter/ASPIRE/aspire/build/ios/iphonesimulator/Runner.app on F6FB781C-D7B0-40C0-8665-6E703C4F7A3C. This is sometimes caused by a malformed plist file:
ProcessException: Process exited abnormally:

下面也是我的 info.plist 文件。我认为错误来自这里
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<key> …我已经能够使用文件选择器包打开我的文件，但我要将结果路径保存到pdfFile变量。
这是变量
File? pdfFile;
我从下面的代码中收到错误
onPressed: () async {
FilePickerResult? result = await FilePicker.platform.pickFiles(
type: FileType.custom,
allowMultiple: false,
); //allowedExtensions: ['pdf', 'doc']);
if (result == null) return;
final path = result.files.single.path;
setState(() {
pdfFile = File(path); //2 positional argument(s) expected, but 1 found. and The argument type 'String?' can't be assigned to the parameter type 'List<Object>'.
});
}
