Question

在手机上启动Flutter应用进行调试（仅适用于Android）时出现错误。运行正常，现在启动时出现此错误：-

Launching lib\main.dart on Android SDK built for x86 64 in debug mode...
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

✓ Built build\app\outputs\flutter-apk\app-debug.apk.
Installing build\app\outputs\flutter-apk\app.apk...
Error: ADB exited with exit code 1
Performing Streamed Install

adb: failed to install D:\flutter\illuminate\illuminate\illuminate\build\app\outputs\flutter-apk\app.apk:

4axwxmIT5fpdidhVYjy4tQ==: Package /data/app/com.illuminate.comcrop-4axwxmIT5fpdidhVYjy4tQ==/base.apk code

这是我在调试控制台上看到的。如何使我的应用重新运行？
