问题
I am new to flutter and have successfully gotten it installed and working on one machine, but when working on this one I am having some issues. It is a fresh install of android studio, flutter, and gradle. The machine is running an updated Windows 10.
The Flutter doctor statement returns an error while retrieving device properties.
C:\Development\FlutterApps\first_app>flutter doctor -v

When trying to run the flutter app on an emulated android instance or a real device I get the same error:

回答1:
Try restarting adb, it's a known issue with the adb daemon service and flutter which you can see on github. it has to be fixed on android side sadly no resolution for near future.
on windows,in administrative mode command prompt/powershell
adb kill-server
and then
adb start-server
if adb is not on path in command line you need to add it or navigate to adb.exe location in windows and run command line/powershell from that path.
回答2:
Another mistake possible is that for a physical device you need to have the file transfer mode enabled (not charging) as well as debugging enabled.
回答3:
So after struggling to get the program working and some more searching, I found a solution to the two issues I was having.
The first issues is android studio would not run unless studio.bat was running, this was fixed by disabling ASLR in windows security settings. (studio.exe/studio64.exe)
The second issue was it could not retrieve device properties, this was fixed by disabling heap protection on adb. (adb.exe)
Post with more details on how to do so: https://stackoverflow.com/a/54164463/4125133

There is a temporary fix you can found in this link https://github.com/flutter/flutter/issues/33938#issuecomment-499250288. It worked for me.
P.D. Maybe you need to downgrade from API 29 to API 28 in your Android Studio.
回答5:
I solved this problem by installing Android SDK Platform-Tools.
Open Android Studio -> Configure (bottom right) -> SDK Manager -> SDK Tools (2nd Tap)
回答6:
cmd on flutter folder: _git pull _flutter channel master _ and flutter doctor
this solve all my problem!!
回答7:
Up to this date, the only way I was able to solve this problem was downgrading to Android Platform Tools 28 from http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
Used the .zip to completely replace the contents of the platform-tools folder located at
C:\Users\[my-username]\AppData\Local\Android\Sdk\
(Bear in mind that the AppData subfolder is hidden).
After that, flutter doctor did not find any issues and I was able to deploy the App in my Android device.

I also have problem i reinstall hole system but problem is still so to solve the problem following steps to be follow:
- Windows: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip
- After downloading past in sdk path and replace to your platform-tools

回答9:
Downgrade Your platform-tools from 29 to 28 use these links.
This is a temporary solution only.

macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

This issue was resolved in a later SDK update.
