如何同时在 Android 和 IOS 模拟器中查看我的 flutter 应用程序 output？

Question

I am using the android studio to develop flutter application, I want to know is there any way I can see my app output in both android and ios simulator also I can perform hot reload on both simulator?

Answer 1

To debug multiple devices concurrently you should set up a launch config for each device that has the deviceId fieldset (this is the same ID you'd pass to flutter run -d xxx). Open the launch config by clicking Debug -> Open Configurations. Add a compound config at the bottom that will launch both (or more) configurations at the same time:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Current Device",
            "request": "launch",
            "type": "dart"
        },
        {
            "name": "Android",
            "request": "launch",
            "type": "dart",
            "deviceId": "android"
        },
        {
            "name": "iPhone",
            "request": "launch",
            "type": "dart",
            "deviceId": "iphone"
        },
    ],
    "compounds": [
        {
            "name": "All Devices",
            "configurations": ["Android", "iPhone"],
        }
    ]
}

Selecting the compound config on the Debug side bar and clicking Debug -> Start Debugging (or Start Without Debugging) will launched debug sessions for each device at the same time.

Yes, there is a way to do that First install android and ios simulator and one by one Flutter run after that when both simulators are running. you can Hot reload from here.

and if you are looking for running both simultaneously then just then select all available devices and run your command. flutter run

Finally, I found a command to run an app in both Ios and Android simulator.

write below command in a terminal where your app is located

flutter run -d all

You can press r keyword in terminal to do hot reload.
