英文:
Flutter app freezes at splash screen (java.lang.RuntimeException: Unable to start activity ComponentInfo)
问题
I am currently releasing my APKs to the stores and I've encountered a problem where my app wouldn't go further than the splash screen. I initially thought that problems is in how overloaded main() function is but then i got logcat.txt from play market.
The problem:

I tried searching for that exception and I found that this is caused by **webview_flutter** package on a newer flutter version, so I removed it from my project, removed **flutter_html** which depends on it, removed all packages that have some connection to a webview at all, but still no result. The up still freezes on a start in most cases.

**得分**: 1
Freeze is gone now, here is how I solved this: <br>
解决方法如下：<br>
Turns out, **Firebase** wasn't set up correctly, if you have the same issue and have **Firebase**, you should check if it is set up correctly. <br>
原来，**Firebase** 没有正确设置，如果你遇到了相同的问题并且使用了 **Firebase**，你应该检查它是否正确设置。<br>
What was wrong: <br>
问题出在：<br>
For some reason (I'm not the only one working on the project), we had
apply plugin: 'com.google.gms.google-services'
inside *android/build.gradle*. So I moved it from there to *android/app/build.gradle* where we apply other plugins such as **'Kotlin-android'** <br>
由于某种原因（我不是唯一在项目上工作的人），我们在 *android/build.gradle* 中有以下代码：
apply plugin: 'com.google.gms.google-services'
所以我将它从那里移到 *android/app/build.gradle*，在那里我们应用其他插件，比如 **'Kotlin-android'** <br>
And then inside *android/app/build.gradle* in the **signingConfigs**, I've added the following:
然后在 *android/app/build.gradle* 的 **signingConfigs** 部分，我添加了以下内容：
implementation platform('com.google.firebase:firebase-bom:31.3.0')
implementation 'com.google.firebase:firebase-analytics-ktx'
So it's like 3 lines of code... **Always** double check your setups in situations like this, or you might have a reputation hit from the client, like I did /:
所以这只是 3 行代码... **永远** 在这种情况下仔细检查你的设置，否则你可能会像我一样受到客户的声誉打击 /:
